Doesn't work for Bikeshed files

[kvark]

I'm not seeing any effect of the plugin on ".bs" files (see https://github.com/tabatkins/bikeshed). Note: it contains both markdown-like brackets, and HTML-like brackets.

Unmatched brackets are not highlighted, even upon saving the file.

Example file: https://github.com/gpuweb/gpuweb/blob/main/spec/index.bs

Note: I do see the plugin working for other files (like ".rs"), so it's installed properly. Using Sublime Text build 4099.
