Edge failures
Environment
https://gitlab.com/eyeo/adblockplus/testpages.adblockplus.org/-/jobs/768081805
Observed behavior
After !109 (closed) landed, sometimes the Edge CI job fails all the tests. Most of them show the error:
JavascriptError: javascript error: browser is not defined
Expected behavior
The CI Edge job should not fail.
Further information
The error could be related with Node12 demanding more resources than Node10.
