Description Simon Fraser (smfr) 2020-05-04 21:56:42 PDT 
Sometimes, after scrolling a <select> listbox (like the Component list when filing a new bug here), you hit the end and the page rubber bands, and then you can't scroll it any more.

To reproduce, you have to hit the top of the listbox and trigger a rubber band on the main page. Then we latch to the main page and never let go.
