548124 - Autoscroll in select popup gives wrong scrolling behavior

Status: RESOLVED WORKSFORME

(Toolkit :: UI Widgets, defect)

Description

[Martijn Wargers (dead)]

See testcase, to reproduce, click on the select, then middle-click in the select drop-down popup.
After that, autoscrolling goes wonky. It seems like the coordinates of the select drop-down popup are used, somehow, to indicate how autoscrolling should behave.

Perhaps no autoscroll image should appear at all, when middle-clicking in a select drop-down popup.

What behavior do you see?
In my case, the drop-down disappears and the page is autoscrolled. I only enabled autoscroll for "multiple" selects, otherwise it falls back to the next overflowing element, which in this case is the window.

Although the mouse s still above the autoscroll icon, the page scrolls to the bottom.

Yeah, the autoscroll speed is wrong. The speed seems to calculated against the select drop-down popup, not the window, it seems.

I'm unable to reproduce this.

I can reproduce.
Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.3a2pre) Gecko/20100223 Minefield/3.7a2pre ID:20100223035408

in browser.xml
Value of event.screenX and event.screenY are changed after the following sentences were called.
 
           this._autoScrollPopup.showPopup(...);

I think that it seems core eventhandling issue.

I still can't reproduce this, neither on windows nor linux.

STR:

- New profile; first run
- Past testcase in locationbar and load the page
- Click on selectbox dropdown arrow
- middelclick on option 19
- move your mouse a little bit upwards

Result: page scrolls downwards.
Expected behavior: unknown. Not upwards in any case. :)

I see another problem:
STR:
- Load testcase
- Open selectbox dropdown
- Middleclick on any option (the dropdown disappears, the autoscroll icon appears and scrolls the whole page correctly)
- Click on the selectbox (autoscroll stops)
- Click on the selectbox again to open the dropdown again
- midleclick on any option (the dropdown does not disappear; the autoscroll icon is hidden behind it but does scroll the whole page correctly; the dropdown is scrolled too, but it floats above the browser window)
