Steps to Reproduce:
Go to edit mode in a module, https://ru.wikipedia.org/wiki/Модуль:Песочница/Carn/Frame for example.
Place the top edge of the editor textbox including buttons near the top of the browser window.
Activate CodeEditor with a button <> in the left top corner, so line numbers appear.
Move text cursor around a bit with keyboard arrows.
Actual Results: the whole page begins to jump up and down a bit.
Expected Results: the page should not twitch jerkily.
Which browser(s) and browser version(s) has this been tested with, and does this happen with all browsers?
Google Chrome Version 83.0.4103.106
json profile from the console:
If you need any more data from the console, I am ready to provide.
Using IE11 in similar conditions does not lead to this error.
I get this error quite often, but not every time in the described conditions, as I understand it for other users, it also happens, but perhaps less often.
I attach a performance profile with built-in screenshots that you can upload to DevTools and see it.
When the cursor moves, only the following parameters change:
ace_layer ace_cursor-layer ace_hidden-cursors
ace_layer ace_cursor-layer ace_animate-blinking
the jump itself lasts about 100ms before it bounces back
