Firestore: collapsed fields re-expand within seconds

**Describe the bug**
In the Firestore UI, collapsing a field on a Document only remains collapsed for a few seconds. This interferes with development and debugging work as fields are jumping around and an already limited data window is filled with unnecessary information.

**To Reproduce**
Steps to reproduce the behavior:

1. In Firebase Emulator UI, navigate to a Document in the Firestore Database that contains a field of type "map" or "array".
2. Collapse the field's value so that only a single line is showing for that field value.
3. Wait a few seconds (seems to be less than 10)
4. Notice the UI refreshes such that the field's value is now re-expanded

**Expected behavior**
The collapsed field remains collapsed as long as that Document remains the one being viewed.
