Make sure that you have some low-end device, e.g. Nexus 5x with Android 8.1.

Scenario :

1. Create a list block with 10 list items
2. Create an image block with some random image
3. Create a paragraph block with some content
4. Create a second list block with 10 list items
5. Create an image block with some random image
6. Create a header block with some content
7. Create a third list block with few elements
8. Start fast typing/removing text from the list block

Result: Cursor will move automatically from newly created block to the previous block
Expected: Nothing odd should happen when type fast
