I made this devlog post.
I have a bunch of image with captions, and I noticed that after the first animated image, all further images did not save captions inside a <figure> tag. I'm not sure what caused it. I know I copy and pasted image links both in html and bbcode form from imgur, and that I hit enter and backspace a lot around the captions. I also tried to center the captions and that didn't work (not sure if it's a bug or it's meant to work that way), so instead I left aligned them and the images.
I noticed that when I upload images no <figure> tag is created. It took quite a while to write the post, so for now I just edited the HTML manually (thanks for that feature!) maybe I'll try to debug it further later.
Edit: and if I hit Ctrl + Z to uploading an image, it seems a space is inserted. I feel like a picky complainer now. Copy and pasting an image with captions do not paste the <figure> tag or the caption.
I'll just leave it here for staff to check and maybe improve the editor in the future.
