Description Telesto 2020-09-13 12:00:13 UTC
Quite some activity on undo deleting a (large) table

Steps to Reproduce:
1. Open attachment 165455 [details]
2. Place cursor inside the table & press CTRL+A twice
3. Insert Table -> Select yellow table style and press OK
4. Press Undo once (and monitor CPU usage)

5. Another route: delete the table
6. Undo (also triggering spell checker dirt flag)

Actual Results:
Undoing causes quite an amount of activity

Expected Results:
What I see passing along in VerySleepy doesn't seem necessary compared to other cases

Reproducible: Always

User Profile Reset: No
