Can we re-review the priority on this and other WebVTT bugs, please?

According to stats by encoding.com, 30% of all caption content that they transcode is in/for WebVTT (30% for SCC, 30% for CEA608, 1% for DFXP). WebVTT is the dominant Web caption and subtitle format now.

WebVTT is now in CR and Web platform tests are failing in FF in many ways - see
https://wpt.fyi/results/webvtt/parsing/cue-text-parsing/tests/entities.html?label=stable&aligned=true
just for the HTML character entities.

It looks like WebKit just fixed, so Firefox will likely soon be the only one failing the WPT.
