Hi Jessie, can you please help me triage this or get this on someone's radar? It looks like we're not invalidating correctly when the user horizontally scrolls in this case.

Kats - can you take a look? Not sure if this would be APZ, technically.

There are actually three different scrollable areas on this page: one covering the whole page, and one covering the pane on the left side, and one covering the pane on the right side. So if you scroll right on the whole page, and then scroll right on the right pane the rest of the content can be revealed. So this seems like an issue with the page itself.

The product::component has been changed since the backlog priority was decided, so we're resetting it.

Set a minimum width on the flexible column to make sure that it will always match the header in width in the event the header is larger than the grid. r=ntim
