I just encountered this issue, and it's pretty annoying, due to its ability to wipe out highlighting for an entire file.

The bug appears to affect everything up until the next where, after which it returns to normal.

Notably, this only happens for class declarations and not instance declarations.

Hmm ... I guess for the time being you can just add the where. For empty type class (instances) it is optional

Note to self: This issue may be fixable, by amending endCaptures to not only trigger on where but also a non-empty, unindented line
