I’m countering a small bug where the collapse property of headers seems to be getting inherited by an image. I’m not sure if it’s just specific to images or can happen to other things like plain text.
Hi, Dimitri!
Many thanks for the video with the explanation 
It looks like the text was removed from the header and the picture was inserted instead
Could this happen?
Maybe we have to make it more clear from our side, but Picture can be a part of header is fact
