But what was the rationale for preventing key events while doing DnD?

I couldn't get that to work properly with FF 3.6 and gave up after a few
crashes and hangs (which admitedly are not the spec's fault).

Why not make the implied drag and/or dragstart explicitely fired when
external applications start DnD in the browser? That might make it
simpler and more consistent.
