Limitation with exporting SVGs over 300mm

Hi, big fan of Flatter!  Super handy for CNC and laser hobby projects!   

I'm encountering an issue limiting the size of an object that can be exported.  Anything larger than 300mm displays the error "no shapes to export, aborting" when trying to export.  Reducing the size or scale of the object will allow me to export it, so the tool is working below this threshold.

I've tested this with a single plane and an array of objects. 

Is this an intentional limitation or is there any way to increase this?  Any help would be appreciated!
