Description

Expected behavior

A black nav bar shouldn't be shown in post previews.

Actual behavior

Post previews sometimes show an unwanted black navigation bar. It looks like this happens after the user has used the Unsupported Block Editor.

Steps to reproduce the behavior

On a self-hosted site connected via Jetpack:

  1. Open a post containing an unsupported block (e.g. an Audio block at time of writing)
  2. Tap the (?) option to open the Unsupported Block Editor (UBE)
  3. Once the UBE is open, close it
  4. Close the post and tap the View button on the post list screen to preview the post
  5. Notice the black nav bar at the top of the preview
Tested on Samsung S10, Android 10, WPAndroid 15.8

Research direction

Start by reproducing the sequence on a Jetpack-connected Android site: open an unsupported block, enter and close the Unsupported Block Editor, then preview the post. Trace the state shared between the editor and post preview, and confirm the preview no longer shows the unwanted black navigation bar after that sequence.
