Mouse scrolling should not close doorhanger notifications

Attached file Page to test out.
On Mac OS X the OS simulates "momentum scrolling" by sending more scroll events after the user has stopped scrolling.

If the user is in the middle of a scroll or finished but momentum scrolling has taken over, a doorhanger notification could be shown and then instantly removed.

Wasn't able to produce a test case but instead a page to test the geolocation doorhanger not showing from a scroll.

My recommendation would be to not dismiss the doorhanger notification on scroll events. It seems weird, since the notification is attached to the chrome, and a scroll operation is easy to trigger accidentally. Clicking in the content area focuses the content, and it makes sense to dismiss the dialog then, but scrolling doesn't change focus (at least on the Mac, you can scroll a background window without changing focus, and I believe the same to be the case on Windows, at least).

Should all panels remain on scroll events, like the site identity panel and the bookmark star panel? I feel like these panels should behave consistently, and right now those panels also disappear on scroll events.
Yes. Scrolling is not an event that should cancel the notification panels, clicking outside them is.
This sounds like a widget level bug, so I'm cc'ing Enn to see what his thoughts are.
<panel> elements close when the mousewheel is used; this is so that autocomplete widgets rollup. However, this probably shouldn't be the case for all panels.

Per comment 3, this makes the mouse wheel to not dismiss arrow panels

I'd rather you did the reverse and checked specifically for autocomplete popups.
The awesomebar autocomplete panel is of type="autocomplete-richlistbox". What should I do for that?
 - match both autocomplete and autocomplete-richlistbox?
 - pr is it possible (and desirable) to match autocomplete-* ?
 - or add a new attribute for mousewheel rollup and check for that
Check that <textbox type="autocomplete" as is done in nsMenuPopupFrame::ConsumeOutsideClicks()
I can't seem to find an association between the panel and the textbox.

nsMenuChainItem->GetParent and nsMenuPopupFrame->mAnchorContent are both null, and the parent of the panel is the popupset, not the textbox.

Aside: Felipe, you asked me in IRC if this was intended to be a hard or soft blocker since the whiteboard didn't match the etherpad. We originally considered this a hard blocker, but the consequences of losing the doorhanger are usually nuisance (failing to remember a password, failing to install an addon), not catastrophic, so we are treating it as a soft blocker (that, like many soft blockers, we would REALLY like to fix.)
The nsMenuPopupFrame::ConsumeOutsideClicks code just looks wrong. It would only ever be useful for autocomplete textboxes that don't specify external popups (i.e. whose popups are dynamically created and placed inside the textbox's anonymous content, which isn't the case for the URL bar), but even then GetParent() on the menupopup wouldn't find the actual textbox, as felipe points out.
OK, so let's just do something simple then. Either just check for a type attribute with any value, the type attribute set to 'autocomplete*' or just use a new attribute 'closeonscroll'. We can find a better solution later.

As the rollup was originally meant only for autocomplete popups, I chose to check for "autocomplete*"

Don't think you meant to do this.

>+    *aShouldRollup = (value.Find(NS_LITERAL_STRING("autocomplete")) != -1);

Instead I'd use:

  *aShouldRollup = StringBeginsWith(value, NS_LITERAL_STRING("autocomplete"));
