[edbrowse-dev] iframe.src = "javascript:false"

[Kevin Carhart]

A site (coscoshipping.com) sets iframe.src = "javascript:false"
and then takes ifr.contentWindow.document, which raises this:

the javascript protocol is not supported by edbrowse

Is this remotely legal for an iframe src?  Anyway, the context for why 
they're doing it appears to be an extraneous third-party library so we can 
table it til it's a blocker of something real, if ever.
