[kuzmany]

@escopecz could you add this bugfix to 2.9.1.
It's really annoying bug, cause transform all videos on website

[escopecz]

I'm not quite sure there will be 2.9.1 or there will be 2.10.0. But sure. It won't do any harm.

@kuzmany @dongilbert data-mautic-video="true" from #4480 and data-mtc="1" are the same?
