State: closed
Merged: No


On tables with a large column count (>20), if a user clicks or double clicks the resize control in the column header, that column can get "stuck" in a resizing state.

This is because the mouseup handler for the element has not been registered in JS (startColumnResize) before the user has released the mouse button.

There needs to be an onmouseup handler registered on the resize control that is also hooked up to stop resizing to catch this scenario.
