Table refresh stack.
This seems to be some regression in Outline. After a node is inserted, the whole table is refreshed as illustrates the attached stack trace.
This can also worsen performance of Outline.
(This was found during examination of issue #225452.)

The table is refreshed as well when column names change.
Changing to P3 - this does not seem to be as severe as an average P2 defect.
Still it's targeted to be solved in 7.4.
