Build error when using template literal with @let or track #60528
Description
Which @angular/* package(s) are the source of the bug?
compiler
Is this a regression?
No
Description
In Angular 19.2 template literals are allowed in template files but when using with @let or track this causes a build error.
There are surely other cases that I have not noticed.
