Describe the bug
When the user has some formatting option selected (bold, italic, etc.) and rotates the device, this options are toggled off.

To Reproduce
Steps to reproduce the behavior:

1. Create a Paragraph block.
2. Tap the bold button.
3. Rotate the device.
4. Notice the bold button is toggled off.

Expected behavior
I expected the button status to stay the same after rotation.

I recently made a change to how landscape is handled on Android so that we no longer extract the editing UI when entering landscape mode (i.e., you could still see and scroll through the post instead of having a full-screen text editing experience in landscape). I believe that may have resolved this issue, but I also think we're going to revert that fix. So although this issue may not currently be present on develop, I believe it will be "back" on develop very soon.
