Oversized image rendering in commit area

[LiveG-Technologies]

Description

When big images appear in the commits preview area, they end up covering a large portion of the screen. Luckily, the branch and fetch/push buttons are on top.

Version

• GitHub Desktop: Version 1.1.0

• Operating system: Microsoft Windows [Version 10.0.16299.248]
• Windows 10 Pro, 2736x1824px screen resolution, Microsoft Surface Pro 4

Steps to Reproduce

1. In a repository, create a big image.
2. Don't commit the image, click on the image's file name on the left of the window.
3. The result will be shown.

Expected Behavior

Images should be resized to an appropriate size (say, 100%) and fit into the area.

Actual Behavior

When big images appear in the commits preview area, they end up covering a large portion of the screen.
