Classifier sometimes stops classifying at some point in the file

[KirillOsenkov]

this is very strange, at some point classification just breaks:

<Project>
  <ItemGroup>
    <a Include="@(b->WithMetadataValue('c', 'd')->'%(e)')">
    </a>
  </ItemGroup>
</Project>

the quote should be blue, and everything after that loses classification.

Strangely, the tagger does have an xml - attribute quotes tag where the closing quote is:

Is there another unclosed tag that overlaps this and goes to the end of the file?

weird, it thinks this is an attribute value:

Aha, it's TextMate, I added a way to see classifications and the last span is all classified as a string (in green):

I found MSBuild.json and I'm not brave enough for this

Maybe msbuild-item-function doesn't support A->B->C?

Yes, feels like msbuild-item-function should be refactored to allow for multiple "invocations": @(A(->F(args))+)
