Transloco

Is this a regression?

No

Current behavior

It seems the alias is lost in some cases. If the page is first loaded, with a component that has transloco signals and scope in the component, e.g.,

providers: [provideTranslocoScope({ scope: 'shared-lib', alias: 'lib' })]
anotherTitle = translateSignal('anotherTitle');

And then, if you go to the page which has the same scope in the providers, the alias is totally lost, and accessing {{ "lib.anotherTitle" | transloco }} will result in an error in the console, and translation text will be missing.

This can be reproduced in the codesandbox I provided. Click on the "Some page" link, and you will see that the translation is not loaded. But, stay on that page, press reload in codesandbox, translation will be there, no errors. Also, if you now click on the link "Home", all is fine, the translation will now work on all the pages.

Expected behavior

Alias not to be lost in any case when using provideTranslocoScope()
