Detailed Description

Whenever a signature image is observed on iPad (it could be a problem on all small screens), whenever the signature image does not natively cover the whole width of the canvas, it's stretched (keeping dimensions) to cover the whole width of the canvas. Making some signatures cover almost the entire screen both horizontally as well as vertically because the images get blown up.

Reproduction Steps

1. Have a signature image (or find a user with a signature) that is small enough to not cover the width of the whole screen.
2. Make a forum post with said signature.
3. Observe the forum post on an ipad (unknown if it works on other devices with a lower resolution)
4. Notice how the image is blown way out of proportion
