1637436 - viewed images do not properly scale: should not maximize width

Status: RESOLVED INACTIVE

(Firefox for iOS :: Browser, defect)

Attachment: screen captures

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:76.0) Gecko/20100101 Firefox/76.0

Steps to reproduce:

• View the image at this URL: http://caseyconnor.org/pub/image/800x1600.png
• rotate phone in to landscape mode
• observe that image is scaled to the full width of the screen
• using a two-fingered zoom, shrink the size of the image
• observe that the image is forced to be the full width of the screen

Actual results:

By forcing the use of the full width, this prevents the user from including more vertical content of the image.

Attached are demonstration screen captures:

img1 -- the image in vertical mode
img2 -- the image after phone is rotated (the scroll is not at the top of the image; not sure if that's a bug in itself)
img3 -- the image after scrolling to the top of the image
img4 -- the image in the middle of a two-fingered zoom -- this is where it should stay, but instead it immediately returns to the img3 state after the zoom is released.

Expected results:

The image should not be force scaled to the full width of the screen if the user has intentionally scaled it themselves: it contradicts a clear intention of the user and only serves to frustrate.

The use-case for me: I sometimes read sheet music from the phone, and it is often more readable in landscape mode, but often requires a slight shrinking of the image to fit more of the music on the screen. This is made impossible by this behavior, which frequently makes a suitable presentation of the image impossible.
