Description
### Version info
**Angular:**
17.0.9
**Firebase:**
10.7.1
**AngularFire:**
17.0.1
**Other (e.g. Ionic/Cordova, Node, browser, operating system):**
Windows
### How to reproduce these conditions
GitHub repo to clone as needs SSR to reproduce
https://github.com/pdela/testing-ng17-ssr
**Steps to set up and reproduce**
Clone the repo
install dependencies
npm run start
### Expected behavior
Angular app to become stable in reasonable time (millis)
### Actual behavior
The problem is that firebase prevents angular app to become stable in client, thus hydration process doesn't start, except after waiting for around 120 seconds
Edit:
Unfortunately I still have this problem in the demo above and in another project ( using angular 17.3.x and firebase 10.11.x) and this time using getDoc method.
I'm pretty sure the problem is originated in firestore SDK, as the 2 pending macrotasks that blocks angular being stable point to a setTimout inside firestore source code.

Research direction
Clone the linked reproduction repository, install its dependencies, and run npm run start. Compare the collectionData and getDoc/getDocs cases while observing the pending Firestore macrotasks that delay Angular stability and hydration. Done means the SSR app becomes stable promptly and hydration starts without the roughly 120-second wait.
