Expand on click lightbox is activated on subsequent block images

[JosVelasco]

Description

If the Expand on click option is activated for a block image, the subsequent image blocks will enable this function even if the switch is not selected.

The blocks above the one that has the lightbox activated won't have this function activated.

Step-by-step reproduction instructions

1. Insert one image block.
2. Insert another image block and enable the Expand on click option.
3. Insert another image block without enabling the Expand on click option.
4. Confirm the third image block has the lightbox enabled on the front-end.

I can confirm this is happening for me and give a bit more details from testing. This seems to be only happening using the Gutenberg plugin so something not in 6.4 but since the merge there.

This happened to me yesterday in my 6.4 walk-through, and I was running the same installation as reported.

Note: this issue is not happening with latest Gutenberg trunk.

It seems like this was addressed in #55120. However, if we want the Lightbox roll-out to be successful then I would prioritize cherry-picking that into a release (if possible) before the final WP 6.4 lands.

@karmatosed @mikachan for visibility.

and @mikachan is already ahead of us all! She cherry-picked the change already. 👏

Closing this out.
