Space before : are removed inside media query

[rczobor]

Version 2.4.8 removes spaces in css selector when inside a media (or @supports) query:

@media screen and (-ms-high-contrast: none) {
    body :focus {
      outline: 2px solid #5e9ed6;
    }
}

The space before : is removed and changing the selector.

@media screen and (-ms-high-contrast: none) {
    body:focus {
      outline: 2px solid #5e9ed6;
    }
}

The space before : should not be removed.

Hi @nethzyr
The same for me even with asterisk.

@media ... { .content :not(...) { ... } }
or
@media ... { .content *:not(...) { ... } }

After compressing:
@media ...{ .content:not() { ... } }

UPD: temporary solution is to use "* *"
@media ... { .content * *:not(...) { ... } }

After compressing:
@media ... { .content * :not(...) { ... } }
