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!

I've added this feature using different code in 16e4942

This correlates to how other inverted and basic inverted styles are implemented and handle inheritance for some cases not available in the PR.

They also use lightPrimaryColor and lightSecondaryColor which are the variations of primary / secondary that are intended for dark bgs.

I've added the necessary corresponding state colors for these inverted colors.
