I'm not sure what the desired behavior is. (i) To silently drop the caption, (ii) to wrap the equation in some sort of float and give it a caption; or (iii) to print the text sans the \caption{·}. (iii) can be archived with math-prefix. (ii) is a bit weird, but could be archived relatively easy, but it's not really what one would expect; it's consistent with how captions work for tables (turned into a float when a caption is present). (i) is also a bit weird, but seems the most reasonable to me. Since I don't know what the correct behavior is, I don't have a patch right now. –Rasmus -- ⠠⠵
