Spreadsheet shows blinking cursor while other applications are focused

[Norbert80]

This issue is unique.

• [X] I have used the search tool and did not find an issue describing my bug.

Operating System of DocumentServer

Linux (DEB package)

Version information

Version 8.1.1.27 (deb)

Expected Behavior

The spreadsheet application should not show a blinking cursor while an other application is focused.

Actual Behavior

The spreadsheet application does show a blinking cursor while an other application is focused.

Reproduction Steps

See attached video: ONLYOFFICE spreadsheet blinking cursor while not focused.webm

Additional information

The word processor and the presentation applications show a static cursor while an other application is focused. I suggest the spreadsheet applications should behave identical.

(There is an old report #1151 on DocumentServer that seems not to address this spreadsheet specific bug.)
