Text justification breaks with large window widths and paragraphs because of an overflow in InlineBoxBitfields::SetExpansion() [1]. See attached screenshot - the text on the second line should be justified but is not.

Repro:
1) download test.html (attached) to /tmp/test.html
2) execute: chrome --headless --window-size=4500x100 --screenshot /tmp/test.html 
3) open screenshot.png

A true fix would require growing the expansion field. Maybe a good-enough workaround would be to clamp the expansion to the maximum value of the field to prevent overflowing.
