When a new lexer is set a lot of (apparently lexer-independent) state
gets reset. This is a feature of the underlying Scintilla
implementation.

Thank you Phil, I did not know that.

The problem is not restyling the margin font after this happens, it's the brace matching that I don't know how to reset back to the normal style?
This is what happens:

How do I switch the brace style back to the first one in the above animation? The first one is the slightly thicker braces, before the button press.

Thanks,
Matic
