EDIT: I wrote up the issue more clearly in a new issue #53054
After taking the VS2022 update 17.5.0 on 2/28/2023, syntax highlighting in Typescript became wonky, as can be seen in this screenshot from an Angular component:

The issue is still present after taking the 17.5.1 update today (3/1/2023).
My coworker who didn't take the 17.5.1 update was able to rollback to 17.4.x to confirm that everything works fine there.
