PremiereMax.com no longer loads properly on ToT. This was bisected to gttps://commits.webkit.org/276031@main.
The change in 276031@main introduced an optimization where reading a non-BMP character that failed to match would allow advancing the character pointer two characters instead of one. That optimization has a bug that causes the problem here. Removing the optimization fixes the issue.
