[FUSE] Model directive contents don't get classified as expected

[davidwengier]

This issue is referenced from a skipped test. The test has been unskipped, so you'll have to take my work for it, but the PR doing so is linked below.

Given:

@model AppThing.Model

In non-FUSE the classifications look like this:

0 1 5 razorDirective [] [model]
0 6 8 variable [] [AppThing]
0 8 1 operator [] [.]
0 1 5 variable [] [Model]

In FUSE, we get only the razorDirective for "model"
