table-row border test case
The original test case used border on the table cells and is no longer reproducible for me in STP Release 131 (Safari 15.0, WebKit 17612.2.2).
However, I am able to reproduce the issue by moving the hover border style to the table-row. New test case for table-row border is attached.
