Steps to replicate the issue (include links if applicable):
- Open some article for translation. E.g. https://en.wikipedia.org/wiki/Special:ContentTranslation?title=Special:ContentTranslation&from=pl&to=en&page=Jan+Pike&targettitle=Jan+Pike&safemode=1
- Start translation (in this case you will have ignore warnings that the article already exists).
- Translate some paragraph.
- Try to select text (or even to place the cursor) with a mouse.
Note that this happens both ways (from en to pl, from pl to en). It seems that target/source language doesn't matter.
What happens?:
Screen flashes, some state changes, something happens with a sidebar. See video below. This happens all the time, even in safemode, so should be easily repeatable. The problem was confirmed by me after a report of another user of plwiki (Archiwald).
Note! There is a problem with the keyboard too. In VE I can use SHIFT+END to select the end of line, I can use SHIFT+DOWN ARROW.
What should have happened instead?:
Should be able to use a mouse and keyboard for selection.
Software version (skip for WMF-hosted wikis like Wikipedia):
I think this might have been broken this year, maybe even in last deployment. I used CT on 21 Jan 2023, 23:38 CET and the problem wasn't there (I'm quite sure I would notice).
Other information (browser name/version, screenshots, etc.):
Firefox 110, Windows 10.
Video - first trying to click (place a cursor), then to select text (part or paragraph).
