(Whiteboard: [PDT+] probable fix by 2/15)
The URL given above produces a page consisting of a form with two text input
fields. Whenever the focus shifts from the first field to something else, the
browser hangs. I have observed this on both Linux and Windows M13 builds.
The html is very simple, so I'll include it here:
<html>
<head><title>Test</title></head>
<body>
<form name="testform">
<input type="text" size="10" maxlength="20" name="t1"
onBlur="testform.t2.focus()">
<input type="text" size="10" maxlength="20" name="t2">
</form>
</body>
</html>
The problem is that when the first field looses focus, the onBlur=... code is
called. This then causes nsHTMLInputElement::Focus() to be called which then
(through nsEventStateManager::SetContentState() and
nsEventStateManager::SendFocusBlur()) sends a new NS_BLUR_CONTENT message to the
first text field. The whole process is then repeated for a few seconds until the
browser throws up.
(By adding printf()s in various places I have verified that this is indeed what
is happening.)
