[Dave Townsend [:mossop]]

Attachment: Bug 1931412: Don't hold test windows alive for cleanup. r=standard8!

browser_scroll_size_determination.js is occasionally leaking browser windows. My theory is that this
is happening because BrowserTestUtils.overflowTabs keeps them alive in order to reset the
scrollbox attribute that it changed and then there is not enough time after cleanup for the windows
to get fully collected. Given that these windows are closed anyway there is no need to actually do
this cleanup step so this allows us to skip it.
