Pbr website displays wrong width

[herr-biber]

Well, the pbr in this image is completely filled, but reproduce this incrementally and look at the bar. It is 40% after the first update.

Steps to reproduce:

uuid=(pbr create 0 4)
pbr update $(uuid) 0 1
pbr update $(uuid) 1 2
pbr update $(uuid) 2 3
pbr update $(uuid) 3 4
