For now, before editing pages with videos (and subtitles) in visual editor I switch into code editor and remove all “defaults” from tracks ?? After making changes in visual editor I switch again in code editor and add all “defaults” back.
I hope video block will be improved soon!

Thanks @bcworkz

In allowedposttags array in wp-includes/kses.php option “default” is included and “track” only occurs once in this file…
