When I add a .png image as a background to a bloc it says “no image” afterwards, the image does appear in the editing preview in Blocs but will not show up in the browser preview.
I also cannot click on it again to load another image file. I can, however, drag another image from the assets window to replace it. If I drag the desired png back into it it reverts to “no image”.
I this a bug or do need to know a trick to make this work?
