Details
User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:84.0) Gecko/20100101 Firefox/84.0
Steps to reproduce:
View any small image by opening it in a new tab, and pinching to zoom.
Actual results:
Firefox zooms the image and the background texture, and immediately creates scrollbars to move around the page --- even though the image itself is fully visible within the screen, no scrolling needed.
Expected results:
It seems odd to me that this scenario would trigger scrollbars. I can kinda understand it when tiny HTML pages (e.g. <body>hi</body>) also cause scrollbars, because in theory the background of the page is something the user might consider worth zooming also. But the image-viewing page is entirely created by Firefox, and a user is clearly trying to view the image, not Firefox's background texture.

Setting a component for this enhancement in order to get the dev team involved.
If you feel it's an incorrect one please feel free to change it to a more appropriate one.

This would likely require changes to the ImageDocument code, which I'm not sure what component it is but I think Layout: Images, etc is it. Not sure how best to fix this. We could maybe have the ImageDocument respond to the pinch gestures and transform scale the image.
