200px padding on bar gauge?

I threw in vmotion stats to the bar gauge and while in edit mode the graph goes from edge to edge but when I save the changes, there’s a huge padding to the label on the left hand side as part of element.style (inline?) with a fixed width of 200px which looks better when I remove it but then the value on the right slides over and it too is in a fixed element (100px.)

Both in Chrome and FF at 90% scaling.

Update - it happens when the graph is squeezed down to where the labels appear next to the graph, if the graph is expanded to allow the labels to be on top of the bar it fits fine.
