User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:9.0a2) Gecko/20111010 Firefox/9.0a2
Build ID: 20111010042022

Steps to reproduce:

I managed to try to reload a page with a post request in it and display the print dialog at the same time.

To reproduce the bug (on mac):
Hit Cmd + P and fastly reload the page with a post request in it (I swifted left with my Magic Mouse).


Actual results:

The dialog asking me if I'm sure I want to resend data and the print dialog are both displayed at the same time.
I couldn't close any of the dialog (clicking and cancel, Print, pressing Return, Esc...) and had to force quit Firefox.


Expected results:

User should be able to close any of the dialog.

I have added a proof of concept (parent.html + child.html).

To reproduce:

1. Open parent.html in Firefox
2. Click "click me". This will:
  a. open child.html in a new tab
  b. open a print dialog for child.html
3. Concurrently, child.html will open an alert

Results: print dialog fails to print anything and also cannot be closed.

This is non-e10s issue.
I can reproduce when disabled e10s on macOS and Linux, but I can't reproduce on Windows.
