            Bug ID: 141101
           Summary: The font color popup is not accessible to screen
                    readers on Windows
           Product: LibreOffice
           Version: unspecified
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Keywords: accessibility
          Severity: normal
          Priority: medium
         Component: Writer

A bug was filed against NVDA which is actually a LibreOffice bug:
https://github.com/nvaccess/nvda/issues/12143.

To reproduce:
1. Open Writer.
2. Press Applications key, or Shift+F10.
3. Choose Font -> Font.
4. Choose Font Effects tab.
5. Tab to the Color combo box and open it with either Alt+DownArrow or Space.

Expected result: Colors should be read out loud, and I should be able to choose
one.
Actual: The Color chooser opens, but NVDA is not made aware of this fact. I
only found out about it by using NVDA's object navigation commands. I was
walking up from the combo box for the color chooser to the Character dialog,
walking to the previous sibling, and again previous sibling, to an unnamed
dialog, going to the first child, which is the Automatic button, and to the
right to find several controls like a combobox with an adjacent expanded list
box with 120 colors as its children, and another combobox with recent choices
in it adjacent to that list box.

There are several events missing:
1. An event on the menu button that it actually expanded.
2. A focus event on the currently selected item in the colors list, or the
Automatic button inside the dialog.
3. A focus and selection event on the newly selected color that I choose when
pressing the arrow keys.
4. A focus event once a new color is chosen and Enter is pressed, back on the
Color menu button in the Character dialog.
Note that, should this kind of construct emit menu popup and such events
instead, these are probably not appropriate since this is not a menu. It is an
expanding combo box with some richer options.

Also, I noticed that the tab key doesn't allow me to traverse to the Recent
combobox once I set focus to that popover dialog. Instead, it autocompletes the
currently selected color.

Additional info: Doing the same on Linux works just fine, so this is only
affecting Windows and the events the Windows layer does not fire.
