Side-by-side diff doesn't display correctly when zoomed out in Chrome (BB-7897)

See the attached screenshot. When I try to load a side-by-side diff, the right side is actually displayed below the left side. This is with Chrome 25.0.1364.172 on Ubuntu Linux. It works fine in Firefox.

Editing to add workarounds:

• Either reset browser zoom to 100%

• Or enable new pull request experience by logging in to bitbucket.org > select your avatar (bottom left corner) > Labs > find and enable the "New pull request experience"
