Fixed in 4e977136d3148c3baa0e03568c7a2c7dc28eea65. Funnily enough, this
wasn't indentation related, but font-locking related. Seems
initialization of the major mode didn't work properly because the compat
check for font lock didn't account for typescript as a language. The fix
was simple enough.

Thanks,
