Since we're in chrome/ anyway, it's probably worthwhile to add the actual PDF
file to chrome/test/data/pdf/, rather than using a data URL.  That would let
people try it out manually.

[wjmaclean, 2015/05/25 17:45:43]

Done.

Does loading a PDF in the main frame have the same bug?  I thought we only used
webview for PDFs loaded in subframes, but I certainly could be wrong.

(Does the dialog actually stay open on line 641 without my fix?)

[wjmaclean, 2015/05/25 17:45:43]

Yes, all PDFs use a webview.
