regex breakdown:
- We should see "new line" or "{" or ";" before regex starts (which is precedes css rule name)
(?<=^|\{|\;) - Regex might start with empty symbols (between "new line / { / ;" and actual css rule name)
\s* - Then it matches css rule name
[_a-zA-Z][_a-zA-Z0-9-]* - After css rule name, there should be ":" symbol (between css rule name and its value)
: - Then it might have some empty symbols
\s* - Then its essential to end css rule, without any characters, which might be interpreted as css value
;
All occurrences of that regex are invalid css properties and have to be removed

The bug is rare, so it worth to check "if original css rules even has pattern of :\s*;"
If it hasn't, then we don't need to execute regex.
This will save some CPU cycles
