NoScript blocks MP4 videos on "Safer" and "Safest" without click-to-play option
In #28720 (moved) a regression in NoScript for click-to-play videos got investigated and fixed. However, there seem to be more cases that are unresolved so far. Examples are:

It seems to be related to MP4. I did not find an older NoScript WebExtensions version where this did work, so no regression range.
That's again easily reproducible in a vanilla Firefox 60 ESR, by making sure everything in NoScript is allowed but media and then visiting the above mentioned URLs.
