The signature image has width of 400px, I do not have "auto-fit" option enabled and the scren you see is when I use volume-down button to zoom out the message as far as possible (then the image is displayed fully from left to right, even with some margin).
but when 1080 physical px is 360 logical pixels in HTML - then the image is displayed in "logical pixels" size (?) - when I enter this message, I can scroll it a little bit right (then I can see missing 40px from the image).
I'm not sure if I fully understand the "logical" pixels idea, but why image is not displayed just like-is in physical size, but in "logical" one?
