Morning,
Is it just doing the stretching in the one-page description editor, or is it also doing it in Preview?
It's possible the editor is allowing the stretch on the visual, but isn't actually corrupting the code.

Oh....and thinking over coffee on best placement of the QR code.
Update:
I just tried the one-page lister with the new table. I started a new listing, switched the editor to HMTL, pasted the code, switched back to Standard, and tried typing in text in the first of the wide lower fields/Colors(s).....it wrapped? Preview was also perfect!

What about placing it in the Store Banner (not the listing banner)? That's got a quick top view so a mobile user can quickly spot and switch. Oh...the code element is 120 x 120, but appears to only really use about 75 x 75 (rest is white space surround), so it's possible it can be cropped to fit location a little better.
