[Laszlo-dev] text selection and links not working in iframe (html element) in Safari

[Henry Minsky]

Well, we're installing the event handlers for mousedown and click onto the
actual iframe element in the DHTML app, so maybe that just stops the event
from propagating into the iframe, in Safari and IE7. I'll set up a simple
test case to see if that is the case. Maybe the whole 'capture/bubble' model
gets broken if it crosses an iframe boundary in the browser.
