[Andrew McCreight [:mccr8]]

This large leak started happening very frequently in the remote/test/browser/ directory on 4/24. See bug 1540949. Looking over the test files in that directory, bug 1546385 changed one of those files on that same day, so it is likely related. ato, can you take a look? Thanks. There's presumably a similar leakcheck intermittent leak out there somewhere, too.

[Andreas Tolfsen ❲:ato❳]

We disabled remote/test/browser/browser_cdp.js because it perma-failed
the leakcheck in bug 1546945 and we thought it was limited to that
test specifically. According to this and bug 1546850, it appears
to happen also for the other tests in the same directory, though
less frequently.

We should disable all the browser-chrome tests under remote/test/browser/
until we’ve had time to plug the leak.
