I am still seeing this issue on beta and test2. On en.wiki, it did not prompt for any CAPTCHA when I added an external link for the first time in a session but after that for subsequent sessions it did.

@matmarex: It seems like the part of this task about switch to VE not working after opening Wikitext editor is still broken, I see this error in the console:

@Esanders: Just a quick question though, on VisualDiff when I click on a reference note it opens a new window, is that a separate issue, or is it fixable by this same change?

got it, Thanks @Esanders.

It does highlight the reference when I click on the footnote though.

So what's the expected behavior now? I see that right now, it does not navigate to any page but stays on the Preview section. Is that the change was about?

This issue is fixed, but there is a new regression:T215367 which seems to be relevant to this.

@Esanders: Sure! I was using Android KitKat on Samsung GT-1905G. I have upgraded the OS to the latest version but still it's appearing the same way for me. Here is the screenshot:

@dchan/@Esanders: The android test device that I have is showing the selection context menu on top of the page, so I can't really verify this. Is there a way to enable the floating native selection context menu on android?

@matmarex: we might have broken something in the process of fixing this :( Reported this regression: T212975

@matmarex: filed this regression today: T212809.

@Neil_P._Quinn_WMF, does this task need to go through QA review?

I believe this was caused by the same problem as T209542. I noticed this behavior when debugging that issue and described it:

(…) Both the original load and the retried load complete, setting up two surfaces (you can actually see the first surface with the old page content appear for a fraction of a second – not that you can tell the difference when editing a real article).

That task is fixed, and so I believe this should be fixed too. Can you confirm?

This is fixed now everywhere.

Verified the fix on Beta, will move it to PM review after checking this on production.

@iamjessklein: Yup! I think @dchan already suggested to have the prototype on our demo page: https://doc.wikimedia.org/oojs-ui/master/

Yes, I recommend user testing against against the current design. This feature should be A/B testable.

The scenario for the test is:

When I find part of an article that I want to edit and click the section editing button ...
I want to click the section editing button and see that editable content secluded from the rest of the article...
so that I can focus my attention on the content I want to edit.

We might want to test these sorts of things:
 
 - Has this iteration improved the experience?
 - Is it easier to find what you intended to edit this way?
 - Are you more likely to complete your edit with this fix?

I'd love review from @Ryasmeen @dchen @Whatamidoing-WMF @DannyH
