optional chaining in template uses 'null', but strictTemplates treats it as 'undefined' #37622
Description
🐞 bug report
Affected Package
The issue is caused by package @angular/compiler or @angular/language-service?Is this a regression?
no
Description
Using optional chaining (or safe navigation operator) in templates uses null, but the language-service and compiler (with strictTemplates) treat it as undefined.
This is not a request to change null to undefined (that's proposed by #34385). Instead I want the static types to be correct so I'm not surprised by the different semantics of Angular's safe navigation operator compared to TypeScript/ECMAScript.
