Fixed ESC handling on constrained dialogs on GTK. We used to stop the entire page navigation previously instead of continuing with other page elements if some can't be loaded. This change makes GTK implementation consistent with other platforms.

BUG=27585
TEST=go to http://www/~thakis/cgi-bin/test.html, press ESC when login dialog appears, observe broken image #1, press ESC on the next dialog, observe broken image #2.
