I have requested @ddbeck's review as they have taken a strong initiative on this project, but any and all reviews are welcome!

Thanks for this PR, @vinyldarkscratch.

I'm working through this and I afraid I don't follow how the commits mentioned for css.selectors.-webkit-progress-inner-element relate to the feature. Can you spell that out a bit more?

The rest of the sources look fine, though I admit I've only partially reviewed this so far (I haven't checked the diff itself to make sure your files match the intent).

Just looked deeper into the git log. Fixed the version numbers based upon further research!

Looks good. Thank you! 🎉
