@Jdlrobson I used the source editor. Is that also a VisualEditor component?

Yep. It's a little confusing but VisualEditor is a project not the actual extension and this tag is the best way to get the attention of the VE team.

@Deskana this is on the mobile web source editor but tagged with VisualEditor because that's how we've been told to file these bugs (see https://phabricator.wikimedia.org/T167078#3319584)

@Jdlrobson Thanks. Now I see it.

I should note that presenting users with absolutely gigantic walls of text like that is a usability disaster and violates some fairly basic tenets of modern web design. Alas, this is not going to change.

It's enwiki-specific, they use a half-screen message while the extension's standard is only one line.

Yes, I'm aware of that. The fact it's enwiki-specific is exactly why it is not going to change.

I tested this again.

The behavior in mobile visual editor is still the same as @Deskana found in 2017 (T167078#3319983), and does not exhibit this issue.

The behavior in mobile wikitext editor is roughly the same – there's still the same error message, although the layout has changed since T167078#3320072 (and I couldn't reproduce the issue in T167078#4289978).

Visual	Wikitext

My screenshot (in visual mode) shows the default error message, which is much shorter than on English Wikipedia, but the text of the message lies within the purview of each site's community.

Given the above, I don't think this is a blocker to T221185: Prepare visual editor to be a default mobile editor (although obviously it would be good to fix at some point).

(talked to @ppelberg, removing as a blocker)
