Despite the initial fix to copy/paste, there still seems to be an issue when trying to copy a large number of rows. This seems to occur when you are scrolled too far away from the starting cell of your selection. The simplest way for me to reproduce this is the select A1, scroll down and shift select A100, and try to copy and paste it. if you scroll back up to the top because trying to copy, it works, but you try to copy while A1 is offscreen, it fails. I’m fairly certain this is related to the same chrome update as before because the issue does not appear in firefox.
