Payment Buttons Block: Undo button will not remove the block

[coder-karen]

What is the issue

On a self-hosted site using the Jetpack plugin, once a Payment Buttons block is added to a post or page it isn't possible to remove it with the undo button. With most other blocks, after adding the block and making none or a few changes, clicking the undo button will undo any changes and then remove the block (as a demo you can try with the Business Hours block).

To reproduce:

• Create a new post or edit a template in the Site editor
• Add the Payment Buttons block
• Click undo
• Verify the block is not removed

Likely next steps

The issue is most likely due to attributes that are being set on first mount, likely within a useEffect. This was the case for the Contact Form Block - #36485 - and Donations Block - #37185
