A cell.tooltip unmount threw while the tooltip was closing.

What happened

The tooltip's unmount threw on the way out. The tooltip still closes and its content is cleared, but whatever unmount was meant to stop - a timer, a chart's animation loop - may still be running behind a hidden box, which is a leak the grid cannot clean up on your behalf.

The fix

The error is attached to the console line. The grid guarantees exactly one unmount per successful mount, so the handler does not need to guard against being called twice.
