I have totally bog-standard CSS. Nothing weird. I've used it before without problems. Now I tried adding layers to it using @layer and started noticing that, e.g., a selector from my reset will go from this:
*,
*::before,
*::after {}
To this in compiled output (using run dev):
*:not(#\#):not(#\#):not(#\#):not(#\#):not(#\#):not(#\#), *:not(#\#):not(#\#):not(#\#):not(#\#):not(#\#):not(#\#)::after, *:not(#\#):not(#\#):not(#\#):not(#\#):not(#\#):not(#\#)::before {
