Sometimes save as png outputs a graph with no text #260

The only graphs I know of where this happens reliably for is jobs day graphs. Nothing about the SVG on these graphs look weird. They were recently re-created for Playfair 2.3 so it's not embedded fonts. Unclear what if anything is different about these graphs from others.

This is definitely about font loading. You can see this by having PT Sans and anything else on the same graph - the pt sans will work fine because it is embedded.

I have an issue in on the savesvgaspng board to see if they have any ideas. Until then this is an open issue - for fonts besides Lato and PTSans, you have to save a graph to PNG twice. It will render correctly on the second save.
