In pre H22 I could simply set some CSS on a UI element in a PyPanel and that worked fine. For example: Would make all buttons have a red label.

But now in H22 where, I guess, the whole button is styled with CSS, setting the color red removes alle existing CSS and now only shows a red text:becomes


A (hacky) fix would be to get the current CSS from the button and modify that but the button has none since that CSS is probably a global for the button class so this gets messy real quick..

So is there a way to layer CSS overrides on top of UI elements preserving the pre-existing other CSS properties?
