Research direction
Start by reproducing the issue in the linked 100W performance demo: hold the mouse on a selected cell and use the arrow keys to move the selection. Trace the table's mouse-selection and keyboard-navigation handling, then verify that the previously selected cell does not retain an intensified highlight and that the current selection renders normally.
