Steps to replicate the issue (include links if applicable):
What happens?:
Nothing happens.
What should have happened instead?:
The user should be able to continue editing using the Visual Editor. This worked before.
Software version (skip for WMF-hosted wikis like Wikipedia):
Other information (browser name/version, screenshots, etc.):
TypeError: mw.libs.ve.SwitchConfirmDialog is not a constructor
I think this is because we merged the VE patch removing the switcher before the train cut, but no the MobileFrontend patch (https://gerrit.wikimedia.org/r/c/mediawiki/extensions/MobileFrontend/+/937154).
Everything appears to be working on beta: https://en.m.wikipedia.beta.wmflabs.org/wiki/Fox#/editor/0
It's my fault from T339871, at first I missed that the task had a MobileFrontend part, and when I realized that, I also missed that the VisualEditor part depends on it.
To resolve it, it'd be easiest to backport https://gerrit.wikimedia.org/r/c/mediawiki/extensions/MobileFrontend/+/937154. Does anyone want to do it? I'm supposed to be on vacation D:
