Docker

Version information

v8.2.2

Expected Behavior

Actual Behavior

Hello team
we found some screen jumping scenarios during our usage of onlyoffice 8.2

First scenario is happening when there are media (images) and tables
Whenever USER 1 cursor stands within the table (and within one page view, not within multi page view) and USER 2 makes changes on top (or may be in any place), USER 1's screen jumps (approximately 1-2 page up)
Please find attached video with images

Second scenario , when there are page breaks - jumping effect only happens when we encounter a page breaker, when some content needs to move from one page to the following one (regarding of where in the doc).
Please find attached video as well

Possible root causes might be different cases , than it is described, but at least, with this steps you can reproduce issues.

Attaching documents as well , that you can have the same test scenarios

As it was torturing me so much, I looked into the code and tried to manage some fixes.

As you guys know a lot more than me from code, can you pls double check the fix on your side and make sure that?

1. this fixes the current problem
