Zooming in design mode then changing images does not properly re-adjust scale

Summary

When viewing designs in an Issue, if you zoom in on one of the design images and then navigate to the next/previous image, if that next image has a different aspect ratio, it will initially display distorted.

Steps to reproduce

Open an issue with multiple design assets of different size
Zoom in on one image
Navigate to another image of a different size/aspect ratio

Example Project

#234082 (closed)

What is the current bug behavior?

The next image displays distorted and must be refreshed before it shows correctly.

What is the expected correct behavior?

Images do not display distorted when moving between those of different sizes/aspect ratios while zoomed in.
