Cannot create blob object

test passed in Chrome but went into error when used in PhotoShop.
[Exception: Error: Invalid 'this' object used in toMethod at i.get type [as type] (uxp://uxp-internal/platformjs_scripts.js:1:5750)

Something feels off here – the error isn’t terribly useful, is it! FYI @pkrishna @Sujai – feels like something that we should improve (either the error if not supported or maybe there’s a bug here)
