HTTP2 enabled - causing mp4 or any other video type "error loading"

[fate8383]

Expected behaviour

when http2 disabled on apache and if module removed from nextcloud it plays

Actual behaviour

HTTP2 enabled - causing mp4 or any other video type "error loading"

Steps to reproduce

1.a2enmod http2
2.add to vhost
ProtocolsHonorOrder Off or On
Protocols h2 h2c http/1.1
3.play from web any video file

is this something with my setup or is it a bug? It plays/previews all fine when http2 disabled, it previews but gets error loading for all video types
