1747682 - window.print() followed by window.close() is not waiting for print to finish (again)

Status: RESOLVED INVALID

Description

[Jonathan Watt [:jwatt]]

Bug 1662975 intended to fix:

newWin=window.open();
newWin.focus();
newWin.print();
newWin.close();

to wait until the print had completed. But it seems broken (again?).

nsGlobalWindowOuter waits for bc->IsDiscarded()==true:

But that bc is discarded shortly after the tab modal door hanger is opened.

Works here? I don't see the tab being closed instantaneously when I run that on the console, what am I missing?

(We have tests for this fwiw, so I'm curious about how are you reproducing this)

Attachment: testcase (a second tab should open, and print preview should open in it)

This repro's for me in Firefox 95 on Fedora.

Well, that's a slightly different test-case as the window you're trying to print is the initial about:blank (Chrome seems to try to print about:blank there)

Bah, indeed. Sorry for the wasted time. :-/
