JS Add-in Outlook interface bug

Our organization has an Outlook add-in written in React. Not so long ago, a bug appeared when you open the letter completely and open the taskpane setting, part of the letter management interface freezes in the same place, that is, overlapping part of the taskpane. Applicable only to Windows clients, no problem was noticed on macbooks.

Also, this bug does not happen all the time, but periodically.

Is there any solution to this problem? Is it possible to change some parameters in the manifest?
