Process group background image when saving theme

[pbking]

When saving a theme with "localize images" selected the background image of a group block should be included.

To test:

• Edit a template in a theme and add a group block
• Add a background image to that group block
• Save your changes (to the user space)
• Using CBT save your changes (to the theme). Make sure "Localize Images" is selected
• Observe our theme files. Note that the template that was edited uses a pattern, the pattern has the group block with an image referenced from the /assets folder
• Export the theme. Note that the template, pattern and assets are correct

After following the test steps provided, I somehow end up with an error when trying to export the zip file.

POST http://localhost:8888/index.php?rest_route=%2Fcreate-block-theme%2Fv1%2Fexport&_locale=user 500 (Internal Server Error)

As far as I can. tell, rest_route has no value assigned to it on that URL. Not sure how it's related, but going back to trunk everything works normally. Any ideas?

I suspect the error was the same as was fixed here.

That fix was merged into trunk, but this work was branched from trunk before it was merged. I have rebased trunk and expect it will work as expected now.

Working as expected 👍
