Which @angular/* package(s) are the source of the bug?

Don't known / other

Is this a regression?

Yes

Description

edit: it's just provideAnimationsAsync(). Removed it from the module and now the styling worked, and I removed it from the standalone app and it worked.

Module based apps seem to not have style changes applied when a style is changed in a component (inline style or file-based style). Same applies for module based but in a standalone component... and even an app fully converted to standalone from what I can tell?

Fully module based

Problem component is a standalone component inside a component used in a module

(edit: see first comment by me, I realized the problem)
I converted the whole app to standalone and there is still an issue. But I have had working fully standalone apps before with the latest patches, so I must be missing something. But I can't tell what is missing between those fresh ones and this example. I even cleared .angular/, restarted the serve server, re-opened IDE, and even tried in a different browser from the other tests

(edit: see first comment by me, I realized the problem)
edit: here is a repo I used for a different issue a couple days ago - but in a new branch issue-59640-comparison-never-module. It was and still is in a working state with the newest patch versions. I made the same component as the above examples in this app that never had modules, and it has no style issues whether it is file-based or inline style https://github.com/msmallest/hmr-issue-multiple-components/tree/issue-59640-comparison-never-module. I will take a closer look at the difference between this and issue2--fully-standalone later, but between this and the other issue I'm a bit confused at the moment.
