Using Esc to close Jigsaw UI does not save changes

Steps to reproduce:

1. Place a jigsaw block in the world and open the UI by interacting

2. Type “this message will disappear” into the “Target Pool” field.

3. Press Escape on the keyboard (or press the < icon in the top-left of the UI) to close the window

4. Interact with the jigsaw block again to open the UI and observe the contents

Result: The “Target Pool” field does not have “this message will disappear” as its value.

Expected result: The “Target Pool” field says “this message will disappear”.

Notes:

Closing the UI with escape will save the contents of command blocks and structure blocks so I expect parity in UIs and keep closing the UI without saving. This closing issue is also how Bedrock edition command blocks USED to behave when they were first added, and were changed to escape saving several years ago.
