🐞 bug report

Is this a regression?

I'm doing a new project (Angular 18) based on an old project (Angular 14), then i have no idea if it worked in any versions after the creation of Signals.

Description

When creating a class with the directive decorator and adding inputs that are signals, extending it in another component and then trying to use that component in the HTML, the inputs from the base class are not visible.

Bug Type

This bug prevents the VSCode autocomplete/sugestion to show the inputs from the extendend directive and the possible values in it.

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

Reproduction

https://stackblitz.com/edit/stackblitz-starters-bdy9gh?file=src%2Fapp%2Fbutton%2Fbutton.component.ts

This code was tested in Webstorm too and the autocomplete/sugestion worked fine (not by be, but a moderator from Angular discord, i dont use Webstorm).

Expected behavior

All signal inputs from extended directives should be recognized when using autocomplete/sugestion.
