Describe the bug

In the mobile native version, we only cover the functionality of rendering the synced pattern. We don't support yet editing the content. However, its content might change locally due to side effects triggered during rendering.

As an example, having an Image block with a URL that doesn't contain the query parameter w (width) leads to an update. In this case, the Image block sets the width based on the size attribute and updates the URL. This update makes the editor crash with the error undefined is not a function.

To Reproduce

Preparation:

1. On a web browser, navigate to the patterns page.
2. Select the WP.com site for testing.
3. Click on "Add new pattern".
4. Add a title.
5. Add an Image block.
6. Edit the HTML of the Image block and remove the query parameters from the image source (e.g. ?w=1024).
7. Publish it.

Steps:

1. Create a post.
2. Tap on ➕ button.
3. Tap on "Synced patterns" tab.
4. Tap the item created in the preparation section.
5. Observe that the editor crashes.

Expected behavior
The editor shouldn't crash when using synced patterns.
