Description
I have tried tokenizeLine2 method to highlight some codes, but find it cannot recognize any excluding scope selectors(like string - meta.template.expression) in *.tmTheme files. This kind of scope selector are useful in some cases, so could it be supported?

Research direction
Start by tracing how tokenizeLine2 parses and applies scope selectors from *.tmTheme grammars, focusing on selectors such as string - meta.template.expression. Compare the current selector behavior with the requested exclusion semantics. Done means excluding the specified scope produces the expected tokenization; the issue names no tests or files to run.
