User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.3a1pre) Gecko/20100107 Minefield/3.7a1pre ID:20100107065333

Long scrolled Bookmarks menu scroll-up a line immediately when mouse move from menu to menu popup after open the menu popup.

When I move mouse pointer from a menu to menu popup, The mouse pointer will pass by over a scroll button, but a scroll button becomes active immediately then and scrolls.

In this case I think that I should make delay time to start scroll.

This problem does not happens on Namoroka.

Reproducible: Always

Steps to Reproduce:
1. Start Minefield with new profile
2. Make sure much enough number of bookmarks to scroll menu popup
2. Open any bookmarks (Bookmarks Menu, Bookmark Folder , Boookmarks Widget)
3. Scroll menupopup and close the menupopup
4. Open the menupopup agein, and  move mouse pointer to menupopup(The mouse pointer cannot but pass by over a scroll button then)
5. Close popup and repeat step 4

Actual Results:
 Long scrolled Bookmarks menu scroll-up a line whenever I open up a bookmarks menu and go to the menu popup.

Expected Results:
 Long scrolled Bookmarks menu should not scroll immediately when mouse pointor moved from menu to menupopup.

Candidate:
Bug 534183 - Autorepeatbuttons in menus shouldn't have any initial delay

I think that behavior is not intentional.

sounds line annoying

Comment 4

[Markus Stange [:mstange]]

Ouh... hm... why isn't the menu scrolled to the top when it opens? Then we wouldn't have this problem.

Scroll is persisted when menu is closed and reopened (I think we don't do anything special about it, sounds like a "feature" we just inherit from scrollbox). Actually I don't know if that's by design, but I'd find boring to have to scroll to the desired position every time I open it.

While annoying, I do not think we should hold the whole release for minor UI behavior that doesn't prevent the actual interaction that the user is trying to do (open a bookmark in a folder).

>(open a bookmark in a folder).
This is nothing help.
it is annoying bookmark folder on bookmarks toolbar.

Why need bug 534183? what is purpose of bug 534183?
I suggest Just back out bug 534183 and 534416. Is there any problem?

Is this still a valid bug? I don't see it in latest 22.0a1 nightlies and have not in fact seen it before in previous versions either.
