Comment:
It seems that this is not really a problem, even though the behavior is
confusing when electrolysis is enabled.
Testing by dragging from Tor Browser to another application shows that our
filtering '''is''' effective in Tor Browser 7.x (Kathy and I tested by
dragging from Tor Browser to Firefox). So there is not a potential proxy
leak.
The confusing part is that when electrolysis is enabled, the drag filter
does not affect the data that stays within the browser (e.g., if you drag
between two Tor Browser windows). The content process must have its own
copy of the transfer data which is not subject to filtering via the `on-
datatransfer-available` mechanism. I think this is okay (although arguably
it is an upsteam bug), so I am going to close this ticket again. Please
reopen if you disagree.
