Consider outline not following border-radius a partial implementation

[cpmsmith]

Summary

This information is currently in the data, but as a note. It's not tagged to specific versions, either, which means when scanning, for instance, the browser compatibility table on MDN, the Safari column looks the same as browsers which have implemented this. Now that the spec says this should be done, I think it's reasonable to consider it a partial implementation if it isn't done.

Test results and supporting details

The WebKit bug in the note got marked as a duplicate of this bug, so I updated the link.

Also note that on the browsers that have fixed it, I didn't put a version_removed property on the partial implementations, only a newer support statement. That seems to be valid, and I'm not totally clear on the semantics of having it vs. not having it, so let me know if I should add it.

Hi there, thank you for your PR and welcome to BCD!

I'm down for converting this from a note to partial_implementation; it's a pretty severe caveat. We should also add a version_removed for when the partial implementation no longer applies.

Thank you, LGTM!
