At the moment playback of videos will be paused when the layer is disabled or opacity is 0%.
To make it more confusing videos keep playing in the media preview.
Videos with audio always continue.

In most cases this would make much sense.
However it would be consistent to have a "link playback to surface opacity / never stop playback" like you have it on videos with audio.

In my case I had to playback videos on multiple layers in sync while switching between the layers during playback.
I solved it by controlling alpha via a 2D-shaderFX which does not stop playback.

It would also be possible to have some dummy surfaces with the same content and always visible.
However doing it this way felt too messy.

This behaviour remains the same with MadMapper v6.

In my case, I have multiple subtitle videos playing back on top of a show inside a timeline.
Normally, they are turned off (opacity = 0).
If I enable them during playback by turning on the opacity of the selected language, they just start from the beginning, even though the playhead inside the timeline has already proceeded.
