Aframe inspector: glTF export button broken/ not working as expected

[Pluto8195]

Trying to export my aframe scene using this button was not initiating a download at all,

Instead I selected the entity and exporting that as a glTF using the button on the right and it would download

attempting to re-display the model in aframe was causing issue and I was advised to try viewing it on

to which the response was missing texture:

A-Frame Version: 0.8.2
Platform / Device: OSX chrome

I think the inspector should be changed to export the .glb variant of glTF, with embedded images by default.
