If I scroll directly after resizing the column, the viewport is frozen for about 3 seconds.

I didn't test, but seems like a regression with culprit commit, so I cc author.
Comment 7 Rafael Lima 2022-06-01 20:34:25 UTC 
If I scroll right after resizing column A, it freezes for about 1-2 seconds.

This seems like a minor performance issue. Certainly should be improved.
