Description

As a translator, I would like to type the translated content without having to scroll the page to see where is the cursor. However, during the translation of the article Web of trust from English to Portuguese, this scrolling happend a lot (say, after any key press which added or removed content). This was annoying and counterproductive.

The behavior is also present when translating other articles (e.g. Riemann hypothesis, Universal algebra).

I got the same problem when translating Pratt & Whitney R-1340 Wasp. I got several console logs error (which attached to this comment as .png file); it looks like a issue about code error rather than a problem about browser.

I'd be happy to see it's solved, because it's so annoying and I cannot translate.

Note: And also, when trying to save, I additionally got this console error:

For info - I get this problem translating an article without an infobox.

I've just seen it happening again to two people in Chrome 89 on Windows and Mac in translating the articles Elaine de Kooning and Lorraine O'Grady from English to Hebrew.

Both people tried installing Firefox, and it stopped this unwanted scrolling.

Fixes for T285860 seem to have solved the scroll jumps. We got confirmation form one user, but feel free to reopen if the issue persists in some other cases.
