46681	Update mediaelement.js to fix Vimeo auto play issues.	danieliser	adamsilverstein	"WP core currently includes mediaelementjs v4.2.6. 

Due to recent browser changes Vimeo videos no longer will auto play and often get errors.

A patch was made for this by adding allow=""autoplay; fullscreen"" here 12 days ago: https://github.com/mediaelement/mediaelement/issues/2618

I propose either:

- Updating this dependency to the latest master branch which is currently [6 commits](https://github.com/mediaelement/mediaelement/compare/4.2.9...master) ahead of the latest available release.
- Updating this dependency to the [latest release](https://github.com/mediaelement/mediaelement/releases) (v4.2.9) & manually patching the [6 commits](https://github.com/mediaelement/mediaelement/compare/4.2.9...master) as needed.
- Manually patching the existing version included with WP core to include this and a few other improvements based on changes to modern browsers over the past year.

Master is stable from what I can tell, but as its not versioned and I'm not sure if core would directly accept it without its official release.


This is the specific patch that fixes the Vimeo issue: https://github.com/mediaelement/mediaelement/commit/e84fa56ced5653408203dd0f0db76a05af497720

Personally since core is on 4.2.6 I see no reason we can't feasibly update to the current master branch and mark it as 4.2.9 so that in the future updates will work fine."	defect (bug)	closed	normal	5.3	External Libraries	5.1	normal	fixed	has-patch needs-testing
