anonymous functions cause Event problems after switching windows

Adding anonymous functions as part of Events to an element (using
addEventListener) works great initially.
Problems arise when:
1) using a page that includes anonymous functions as Events, then
2) switching to do something in another Mozilla window, then
3) returning to the original page and triggering the Events
Usually, the anonymous-function-based Events just stop working (until the page
they are on is reloaded.) But often Mozilla crashes shortly after trying to
invoke the anonymous-function-based Events, as well.
Here is my test case:
<html>
<head>
<title>DOM anon funcs added-events-after-window-switch bug isolation</title>
</head>
<body>
<div id="container">click here to change text</div>
<script>
function test_func () {
if ( container.toggle ) {
container.innerHTML =
'some placeholder text for state one';
container.toggle = false;
} else {
container.innerHTML =
'not really very different placeholder text for the other state';
container.toggle = true;
}
}
var container = document.getElementById ( 'container' );
container.toggle = true;
// this works:
// container.addEventListener ( 'click', test_func, false );
// this doesn't after doing anything in any other window
container.addEventListener ( 'click', function() { test_func() }, false );
</script>
</body>
</html>

I see this with a Linux cvs build from 2001-02-05 morning.
Steps to reproduce:
1) open two mozilla windows
2) load http://mozilla.org in window #1
3) load the provided testcase in window #2
4) follow a link in window #1
5) click on the text in window #2 and watch it not change.
setting status to new.

I just attached a test case that shows the same behavior with a named, nested
function definition, rather than with an anonymous function.
Named and nested functions seem to work in some sections of my code. But in
other places they exhibity the same problem as the anonymous functions. I
haven't been able to figure out how to know why some work and some don't -- but
the test case does reproduce the problem behavior.

I believe both of these cases are dupes of 31847. Definitely the first case,
probably the second as well. This is scheduled to be addressed soon.
