It looks like the color is off in the second photo. I'd rather not merge this until we can figure out why, don't want to break themes.

[Nickbert7]

My intention was just to remove the special handling for chrome... but somehow also Firefox has no blur...

Without the change:
Chrome:

Firefox:

Edge:

It would also be fine for me to remove the blur completely, it should just look the same within every browser...

Approving because the code changes seem fine. I'll have to look into the CSS eventually though, it looks like the color changes for blurred items.

Line 268 in dcd4a76

@supports (backdrop-filter:blur(10px)) or (-webkit-backdrop-filter:blur(10px)) {

Themes seem to specify this, so if this breaks a theme, it is a problem with the theme, not this change.

Browser compatability isn't good however: https://developer.mozilla.org/en-US/docs/Web/CSS/backdrop-filter#Browser_compatibility
