[Button] Basic button groups render inconsistently

[moenth]

In particular, basic button groups do not render correctly when a color is applied to the group, but do render correctly when color is applied individually.

I'm familiar with this issue, but I don't know of any good way to solve without a lot of code duplication. PR welcome.

There has been no activity in this thread for 90 days. While we care about every issue and we’d love to see this fixed, the core team’s time is limited so we have to focus our attention on the issues that are most pressing. Therefore, we will likely not be able to get to this one.

However, PRs for this issue will of course be accepted and welcome!

If there is no more activity in the next 90 days, this issue will be closed automatically for housekeeping. To prevent this, simply leave a reply here. Thanks!
