don't zoom in/out when dragging solo image

[jedediah]

When a large image is being viewed alone, the default action of zooming/unzooming is not prevented by the standard mechanism. I don't know off hand how to fix this.

IMHO this is the same behaviour as with pasting the contents of the mouse cursor into the currently-focused textarea – the middle click is not prevented (hence the contents get pasted or the image gets zoomed).

it's different from a technical perspective.. theoretically, it should work but I think there may be a chrome bug here

Ah, right – I can see this after #19 is fixed here.
