Bug#888636: epiphany-browser: Can't get quality above 360p on Youtube

[Byron]

Package: epiphany-browser
Version: 3.22.7-1
Severity: normal

Dear Maintainer,

First I should make it clear that although I am running Stretch, I downloaded
and installed Epiphany from Flathub in order to get the latest stable version
(3.26.5.1, to be exact.) In case you need to know, I'm using a 1280x1024
screen.

I went to Youtube and watched any video. On the version of Epiphany which comes
with Debian (3.22.7), I can get up to 720p resolution on videos that are shot
in 1080p or 4K, but never above 720p. On Epiphany 3.26, I'm unable (as of yet)
to find out how to get a resolution past 320p.

I tried both Xorg and Xwayland with the same result. I'll try more as more
ideas slowly come to my brain.

I do a lot of media consumption so it would be nice to have sharper video.

Thanks for your time. =)
