Critical Bug: Uncaught exception thrown in posthtml-match-helper due to pseudo selectors

[titanism]

You need to strip pseudo selectors before passing them to posthtml-match-helper.

Otherwise an uncaught exception is thrown, because that package creates a new RegExp instance whereas the string has unescaped ) and ( parenthesis.

See posthtml/posthtml-match-helper#8.

Ignore the above - we don't need to inline CSS anymore, since a majority of clients now support it, so we're dropping inline CSS support in our work. Thank you though.
