But I somehow feel (I may be wrong too!) that the caption now feels as if a different element or normal text. Please check here is a site that has the original caption before WP was updated and here is one that is using the new code).
Do you not see a bit of a gap between the image and caption in the new one than the one with old code?
P.S. What else “markups” were affected by the new update? I would appreciate it if you could point me to a list because I want to correct them even if I haven’t noticed them in the site yet.
