Pixie Trying to Parse SVG Viewbox as Int

[Icosahunter]

I have a test SVG image with non-integer viewbox size, and when trying to read this with pixie-python I get the following error:

strutils.nim(1072)       parseInt
invalid integer: 215.9

It seems to be trying to parse it as an integer, but I don't think that's necessarily a requirement for SVGs. I assume this is because it needs to have integer size for exporting to a raster image? In which case it should probably be rounded or something?

here's the full SVG that I was trying, in case that's helpful:
