bug(theming): Can't find stylesheet to import

Reproduction

After updating to v13 this morning, which removed all of the tildes from mat @use statements, our library isn’t building (via ng-packagr), saying it can’t find the stylesheet. If I add the tildes back, it builds fine. Using without the tilde is working ok in the context of an application, but our library builds seem to still need them. This causes a really ugly catch 22, since our styles can’t have tildes to work with applications, but need them to work with the library build.

Actual Behavior

------------------------------------------------------------------------------
Building entry point '@fabric/components/breadcrumbs'
------------------------------------------------------------------------------
× Compiling with Angular sources in Ivy partial compilation mode.
Can't find stylesheet to import.
  ╷

  │ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  ╵

Environment
