JScherer-WMF added a comment to T428610: Images are being skipped for no apparent reason.

Took some prod debugging as the the production code path is different than the local development path, and the former also includes a comparison between the image’s src (where some characters, like comma, are encoded) and the filename; unless they match, the image is not included, as is the case with both of these examples.

Given our goal is feature parity with the Mobile Frontend viewer, should we match their existing error display method, or is it okay to introduce the Codex Toast component?
Can you confirm where to display the error message? @JScherer-WMF

Legacy version:
The Mobile Frontend viewer displays the error message.

JScherer-WMF added a comment to T423110: [Share Highlights] Add or update the share title.

@JScherer-WMF @SherryYang-WMF When sharing, we feed the native share functionality 3 pieces of info: a title, text & the dialog image. These look something like this:

files: <the dialog image>
text: '"Whatever text I just selected, or the intro text"\n\nRead more: http://localhost:8080/wiki/My_page?wprov=shhu0#:~:text=Whatever%20text%20I%20just%20selected,%20or%20the%20intro%20text'
​title: 'Quote from "My_page" — Wikipedia'

The title seems to be ignored often, which begs the question: is there any important information in there that we may want to move to text instead?

JScherer-WMF added a comment to T387382: Making "Automatic" color option the default .

@JScherer-WMF @ovasileva this poses twos question:

  • given what we saw with roll out (interference with browser extensions/people unexpectedly getting dark mode) would we ever re-consider making "automatic" the default

I'd be curious how many people have changed the default light setting to automatic since launch. If there's a meaningful adoption of non-default colour settings since launch by logged out readers, I think it's worth pursuing. If not, we should keep the default as is. We can discuss what "meaningful adoption" would look like in this context. One important nuance is that Wikipedia's brand is very much tied up with black text with blue links on a white background, even more so than with the puzzle globe logo. My intuition is that casual readers who are new to the site or do not come very often would lose trust/confidence in the wikis if the interface were presented to them in dark mode without them expecting it. This represents a significant brand risk.

JScherer-WMF added a comment to T419740: Image Browsing: Port Carousel component to MMV.

Just wanted to document the tweak to the carousel designs we spoke about before, but I can't find any records of it. In user testing, people didn't know that more images were available in the carousel unless one of them was overlapping the right side. Correct me if I'm wrong here, but since we decided not to crop carousel images to a uniform width/height, we don't have any way of knowing whether or not more images are "hiding" off the right side of a reader's viewport.

unless @JScherer-WMF feels strongly otherwise, I would like to propose that only the top two bugs are launch blocking and the others are nice to have (maybe we get to them now that we've moved launch out by a day but if not we can still go), so please work on fixes in this order: #2, #1, the rest. thank you!!!

UI bugs that I found:

  • When you deep link into the page, whether with the ToC or otherwise, the scroll position of the ToC defaults to the top. Whatever the active section is should be in the center of the ToC.

Ok, so lemme zag on this a little bit. We know readers are scanning text looking for links. Why not surface the 3-5 most-clicked links in a long section at the top of that section? Maybe we spike on what kind of section-level data we can get? This is a concept from last year that I adapted to show how this might show up:

For now, it might make sense to spike the highlight interaction without specifying exactly what we'll put inside the module that pops up when a user highlights something.

+1 for the sticky header option looking more feasible, and it looks pretty neat!

I'm not personally a big fan over floating buttons (option #2) obscuring my content, but that's very subjective.
My main concern with that option is the "search" addition: I would expect an in-page search here, but that feels like a can of worms:

  • in-page search would behave differently from regular search (direct text match; no stemming, keywords, wildcards, ...)
  • would require some additional UI elements (e.g. button for navigating to next match)
  • does it find hidden text (e.g. within collapsed sections) or not? (window.find() does not), and if yes, how do we surface it?
  • window.find() is not a standardized feature

Another good option with less fiddly interaction design would be to have a floating action button with search and contents buttons.

I did some design exploration on this yesterday. The appearance of the ToC pane itself is less of a worry to me, we can either adopt what we already have or re-build it using codex. I'm more concerned with IA and scrolling interaction.
