Subbutton Icon Colors - some are dark, some are white [2.5.0.beta.8]

Describe the bug
The subbutton icons are now all dark. Not sure if this was a style choice or not. Either way there is a bug because the new coloring is not applied to all subbuttons. FWIW I liked it better when they were white but I'm sure there is a CSS var for me to restore my preferred color if this was intentional.

When I toggle off .bright-background it goes to the old behavior.

To Reproduce
Use my yaml, swapping out for entities that exist for you. Observe their colors in 2.5.0.beta.7 vs 2.5.0.beta.8. Expected behavior
I expect the icons to be white or at least consistent.

Screenshots
Top is dark mode and bottom is light mode.

For anyone that finds this, heres the style to patch it (I'm sure it could be optimized but it works for me):

  ${(() => {
    // https://github.com/Clooos/Bubble-Card/issues/1343
    card.querySelectorAll('.bright-background').forEach(element => {
      element.classList.remove('bright-background');
    });
  })()}

I will probably rework that a bit, this was supposed to only improve readability when needed, like a white icon on a white button.
