Thanks for checking that @gappiah. I see that. Hmm. Not sure what’s putting that in there.

In fact, if I edit the HTML of the block and remove the invalid style attribute and save the draft, the “Attempt Block Recovery” error immediately appears.

Choosing the three dot menu > Resolve reveals an interleaving of the characters of two class attributes:

size-large

and

aligncenter

I don’t think that’s necessarily invalid, but it sure is unexpected.

Correction: the images do not have “captions”. Mis-typed as “comments.”
