Additional Context

The relevant regexp is here: https://github.com/microsoft/monaco-editor/blob/main/src/basic-languages/shell/shell.ts#L162

Perhaps the regexp, instead of /-+\w+/ should have a whitespace positive lookbehind? e.g. (?<=\s)-+\w+. I realize that this runs into problems with Safari and old IE... I am not familiar with the internals of monaco-editor, but perhaps there are already runtime guards in place that could be used here.

Or maybe something like [/(\s)(-+[\w-]+/, ["white","attribute.name"]]... but here my knowledge of monaco-editor source is too shallow at the moment to say with any certainty.

fwiw, vscode's markdown preview does not syntax color anything...
