Description (last modified by )
Resolves https://github.com/WordPress/gutenberg/pull/55217
When rendering images with the lightbox "expand on click" function enabled, if an image block is encountered with no image (for example, a block was added but no image was ever selected), then WordPress would create a warning that an "undefined array key 0" was being accessed because the server code assumes an IMG element exists in the block's HTML.
In this patch a check is performed to ensure that an IMG block exists before processing the block. If one isn't, for any reason, the original given HTML for the block is passed through un-modified.
This patch needs to be backported into Gutenberg from where it's sourced but this issue arose during the WordPress 6.4 beta testing and needs to be resolved immediately in Core.

Hey @dmsnell, is https://github.com/WordPress/gutenberg/pull/55217 the correct link back to the issue in Gutenberg? They seem unrelated.

thank you @hellofromtonya - correct, that was a mistake. I've updated the description to point to the right issue now, which is 55214 and not 55217

Closing since this has been incorporated into Gutenberg and will come over in the next package update.
