Add "max-width: 100%;" to stop large images from overflowing the new rendering engine UI
Summary:
Fixes T13148. Ref T13105. The new document rendering engine for images let them overflow the UI bounds.
Add max-width: 100%; to keep them contained.
Test Plan:
- Viewed a very wide image in Safari, Firefox and Chrome. Saw sensible rendering.
- Also viewed a normal image, saw normal behavior.
