Class composition is broken with "non-word" (
\w
) characters due to the regex used to split tokens.Perfectly valid classes such as
.my-class
or.mycläss
are broken as they get split up.This PR updates the regex to use
\S
instead of\w
which allows these characters and thus fixes the problem.Additionally, a test has been added to verify composition works with a class that contains a hyphen (which fails without the updated regex).
