Display Issue in AB tests

[marcpalmer]

I'm having an issue while using TelemetryDeck Dashboard.

Location: https://dashboard.telemetrydeck.com/o/co.montanafloss/apps/A55C2D85-15B8-4A32-B84E-222700FBE56B/d/7EE42544-781F-42EC-88F0-B54AD0A534B0

When the browser window is narrow, the A/B Test graphs lose their % bars for each of the two samples.
