Editor crashing while creating a new pattern

[bhaveshdesai13]

The editor for creating new patterns crashes when blocks are removed using the list view.

Steps to recreate the issue:

1. Go to ​https://wordpress.org/patterns/new-pattern/
2. Add any block.
3. Open the list view.
4. Remove the block using the block options.
