Subtitles extremely large in vertical videos with vtt.js

[Frenzie]

Description

In for example a 9:16, subtitles might look like this:

And it's not that they cover the video because otherwise they'd be illegible (which might be defensible I suppose): they're just huge because they only take the height into account when deciding how big to be.

Anyway, I'm only opening this issue because I created a PR to fix the problem a week ago. While this repo's seen a lot of activity I'm not sure if anyone follows there. :-) So please look at videojs/vtt.js#69

I consider videojs/vtt.js#69 a proper fix to be clear. But I can't assign anything to anyone here regardless; I'm just a random user. :-)
