OK! we have a much better minimal reproducible case (thanks @cooltey):

Scroll to the top of the tab list.
Start clicking the “x” button to close the tabs repeatedly, even while the previous tab is still animating away.
After a few tabs have animated away, scroll the list up.

Okay, so the stacktraces are probably related to each other. I will investigate further and will see how to possibly fix this.
