postcss-nested and postcss-prefix-selector interact in such a way that the prefix is repeated within each nested rule if it doesn't use the '&' token, causing broken rules
Updating postcss-prefix-selector to ^1.11.0 didn't help. Switching to postcss-prefixwrap could potentially fix it but it looks like it requires '&' inside all nested rules anyway... Not an improvement thusly
It also fixes a few rules that were overriden by WordPress' Admin Styles
