UI: JS code editor has text cursor offset
Open, MediumPublicBUG REPORT
Actions

Description

When I modify MediaWiki:Gadget-LinguaImporter.js (for example), there is an offset between the position of the cursor and the real position of the text. In the screenshot below,

the black arrow show the position where the cursor is while the black arrow shows where the text is written if we type something.
I do not remember it was happening before the new version of Lingua Libre so I guess it is related to the BlueLL skin.

I saw this on other wikis too without searching why.

Retrying now on Wikipedia, on LinguaLibre and on our WikiValley wikis, it seems the issue is linked to the skin: it works with Vector everywhere (on LinguaLibre since it’s still activated), it has issues on LinguaLibre with the skin BlueLL, and IIRC the issues I had in mind could be on other skins like Chameleon (although it works now).
