RTC not working when session goes to sleep #7582
Description
Describe the bug
In a very specific situation, I can’t edit a cell.
This happens when I switch between windows after a period of inactivity.
Is there a way to re-enable editing without refreshing the page?
When this happens, clicking on the cell does not show the cursor, but I can still type even though the cell is not selected.
Will you submit a PR?
- Yes
