I think the increased time will be helpful, as some context the reason this test is failing is that the new babel-scopes and babel-stepping tests are 10X longer than the typical test. We can split them up too, but it is nicer to read it as one test.

It's a slow test, lets skip it on the ccov platforms

the maxruntime for win10 coverage jobs were increased.

Fail reappeared as a Tier-2 failure on m-c Push: https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&revision=44aceee694bec3dc6a7757395d25553ae87ab166 Log: https://treeherder.mozilla.org/logviewer.html#?job_id=171210485&repo=mozilla-central&lineNumber=7364

thanks for this- lets see if this is perma fail in a few days- I suspect it will be high frequency along with other *babel* tests.

There are 47 failures in the past 7 days. Platforms: most of them occurred on windows10-64-ccov debug and we had some occurrences on linux64 also debug.

Arthur, could you disable this for win10 ccov ? similar to the other skip for win10 ccov in the manifest: https://searchfox.org/mozilla-central/source/devtools/client/debugger/new/test/mochitest/browser.ini#138

:jmaher, disabled on Windows 10 ccov. Should we also disable on Linux 64 ccov?

Updated the patch for disabling ccov on Windows and Linux. :jmaher could you please take a look?
