All failures are on Android.

The assertion is

Gecko : [Child 2885, Main Thread] ###!!! ASSERTION: Overwriting an existing document channel!: '(loadFlags & nsIChannel::LOAD_REPLACE) || !(mDocumentRequest.get())', file /builds/worker/workspace/build/src/uriloader/base/nsDocLoader.cpp, line 432

https://searchfox.org/mozilla-central/rev/ebe492edacc75bb122a2b380e4cafcca3470864c/uriloader/base/nsDocLoader.cpp#430-432

Assertion count mismatches were not being detected on Android for some time; this bug was opened shortly after Android assertion counting was fixed: the intermittent assertions seen here may have been happening for a long time.

Avoid intermittent crashtest failures by accepting assertion.

That assert doesn't look related to the encrypted media content of the test file. We can mitigate this with the proposed fix, and I'll raise another bug to investigate.
