Those laws are frequently overturned as unconstitutional, but may still remain on the books because we don't do a good job of clearing out laws that were ruled unconstitutional. As a general rule of thumb, almost every time someone brings an edge case about whether or not speech is First Amendment-privileged before SCOTUS, SCOTUS rules in favor of the speech. (The main exception is speech of students in school.) SCOTUS hasn't specifically ruled on anti-mask laws to my knowledge, but I strongly doubt it would uphold those laws.
