### Feature Type
What does this bug affect

- [x] Angular Language Service VSCode extension
- [x] Angular Language Service server

### Describe the solution you'd like

### Describe alternatives you've considered
-
### Anything else relevant?

Done means function bindings inside SVG templates receive the same highlighting and definition navigation as bindings in HTML templates, with the behavior verified in both listed components.
