@artemiomorales can you look into this?

Pulling in feedback and a question from a separate issue:

I am the developer of an image caption plugin for publishers who need to show image attributions for legal reasons.
With WordPress 6.5, lightboxes no longer show the caption I added to images in the post content since lightbox HTML is not rendered separately.

Ideally, I could add a placeholder for the caption into block_core_image_print_lightbox_overlay() using a filter, but there is none.
Would you be able to provide one?

In a next step, I would need to figure out how to fill it, but the render_block_core/image filter might just be good for that.

@annezazu Thanks for the ping! I'm not sure I have bandwidth to look at this for the upcoming release. To clarify @webzunft, do you need to render the caption inside the lightbox overlay itself? And this was working prior to 6.5?

@artemiomorales

Yes and yes. In 6.4, I just had to place my caption markup close to the image and it was showing up with it in the lightbox.

It might be related to this refactoring that uses a shared HTML for all Lightbox overlays:

• Image block: refactor and remove data-wp-body #58835

Our photographers would also like the caption to appear when the lightbox is expanded for an image.
