20532	Cannot use more than one wp.Uploader (Plupload) instance	kovshenin	koopersmith	"Hey there!

Found this bug while playing with the Customizer's Image control and the image context. Turns out every control will use the same Plupload instance, so the context will be set to the one, specified by the latest control rendered on screen. This verifies that no matter how many ""new"" wp.Uploader objects you create, it is still the same one:

{{{
var u1 = new wp.Uploader();
var u2 = new wp.Uploader();

u1.param( 'some_key', 'first value' );
u2.param( 'some_key', 'second value' );

console.log( u1.uploader.settings.multipart_params.some_key ); // logs: second value
console.log( u2.uploader.settings.multipart_params.some_key ); // logs: second value
}}}

I'm not too confident in my JS skills to handle a patch, sorry."	defect (bug)	closed	normal	3.4	Upload	3.4	normal	fixed		koopersmith
