[snosenzo]

Steps to reproduce

Link to live example: (required)

https://stackblitz.com/edit/github-rerofp?file=src%2FApp.js

Current behavior

Text in contained button is black.

Expected behavior

Text in contained button is hot-pink.

Context

Was upgrading to v6.0.0 and noticed this regression. I don't think it was documented anywhere, but I believe that is should if it was intentional.

Also FYI it looks like assigning color="" appears to give me the desired behavior, but definitely not an ideal workaround.

Thanks for taking a look!
