Offline support for Firebase Storage operations

### Describe your environment

* Firebase Product: Storage

### Describe the problem

From my understanding, Firebase Storage does not yet support offline operations. To give some context, I am trying to implement a feature that allows users to "upload" an image in offline mode, which actually just stores to IndexedDB, and uploads when there is internet connection.

Then I thought, isn't this generally how Firestore works? So my question is: are offline operations coming to Firebase Storage? If not, I'd like to make a feature request on it. Also as a personal curiosity question, what is stopping the team from using the same offline logic from Firestore?

Thanks!
