Issue 128343

Screenshots illustrating the issue

Please notice that I am not one hundred percent sure whether this is
a bug, some sort of side-effect or merely the consequence of my limited knowledge.

I ran test in AOO Writer but the issue occurs in any AOO component.

GENERAL CONCEPT:
place a toolbar in a position over another toolbar's hot spot - could be
an icon in the main part or one in the title bar. Use mouse to highlight the control and then move mouse outside via start toolbar area. 
Another method is to use toolbar's list box control to achieve same effect i.e. that highlighted control remains highlighted.
 
The effect is easy to remove.


I am placing below a coarse description on how to reproduce the effect but the best way to grasp the idea
is to watch/download my video available at the following link:

Steps to reproduce:

(In attached file "Begin2End" on the left you will see my "start screen")

1. Run AOO Writer
2. Make Find toolbar visible
   View > Toolbar
3. Open Navigation toolbar
   Below the Vertical Slidebar click the "Navigation" icon
   between "Up" and "Down" buttons
   Selected shall be "Page" icon.
4. Move Find toolbar in area of icon "OLE object"
   (one to the left of "Page icon)
5. Move mouse into that area
   Icon is selected.
6. Move mouse outside Navigation toolbar
   Two icons remain selected.
7. Let's "go to extremes"
   In well documented Issue 123202 "Multiple conflicting Navigation
   Toolbars" there is a step-wise description on how to display three
   Navigation toolbars.
   You can apply step 4.-6. accordingly to other two toolbars available
   so that in each of them one icon selected is the same ("Page") and
   the other highlighted is different ("OLE object","Graphics","Text
   Frame").
8. Now make two toolbars visible: "Insert" and "Text Object"
   View > Toolbars
9. If you apply procedure similar to point 4.-6. to
   "small black triangle" and "X" you will have two toolbars with
   highlighted icons.
10. Now the final steps
    Make Bullets and Numbering toolbar visible.
    View > Toolbars
11. Place it in a specific position under Formatting toolbar
    Open dropdown list box with font name.
    Move mouse into Bullets and Numbering toolbar to select
    "small black triangle".
    Mouve mouse outside via list box.
12. Place Find toolbar in a specific position under Formatting toolbar.
    Open drop down list box with font size.
    Move mouse into Find toolbar to select "X".
    Move mouse outside via list box.

My main concern is that under normal circumstances such effect is not so obvious.
