Bug Description

Turning into other block types seem to still work fine.

How to Reproduce

Create the text:
1. Create a normal text block.
2. Create a second text block and use tab to make it into a child of the first one.
Use "turn into" from the left handle or right click menu
- Option A: Into a Page
- Option B: Into any Toggle Heading
Undo with CTRL+Z. Both options make the second text block disappear

Converting a Toggle Heading from one level to another and undoing will also delete its internal text.

Expected Behavior

Undoing text transformations should return all blocks to their previous state, children included.

Operating System

Window 10

AppFlowy Version(s)

0.8.7
