Bug by clicking the publish button

When you upload an image, the animation will remain spinning even if the image has already been loaded.

The bug arises when you use the option to select image to upload

This causes that when you give in to publish the page remains blank only with the animation going around.

This happened to me now with a post in which I had about 40 minutes creating it was going to be my contribution to the blog today and it ruined me, really this is very annoying because it does not let you recover the draft making you lose all your work.

I've been waiting for 1 hour, but I'm loading the blank page.
