Navigator object highlight rectangle is visible at unexpected position

[CyrilleB79]

Steps to reproduce:

1. Enable Navigator object highlighter in the vision settings.

2. Open the process list in the task manager:

   • Open Task manager, e.g. pressing control+shift+escape
   • Select the detailed view if not yet activated (press "More details" button)
     • Select the "Process" tab

3. Select more columns in the process list to ensure that not all columns can fi in the Task manager window:

   • Tab to the process list header
   • Press app key and select a new column
   • Repeat column selection many times (4 or 5) to ensure that not all columns fit in the process list width

4. In the process list, navigate by object in the cells of the currently selected line:

   • In the process list, press NVDA+PavNum2 to go to the first cell of the line (usually process name)
   • Press many times PavNum+6 to go to the next cells

Actual behavior:

The navigator object highlighter rectangle moves rightwards out of the list and even out of the task manager window. This happens when the navigator object is in a column that is not displayed in the list because all columns do not fit in the window. If the last visible column is only partially visible, the navigator object includes the visible part of the cell but expands partially out of the window.

Expected behavior:

The navigator object highlighter rectangle should disappear in columns that are not visible.

Optional: If the last column is only partially visible (croppe), the navigator object highlighter should only surround the visible part of the cell.

Analysis

The cells in the invisible columns should probably have INVISIBLE or OFFSCREEN state; for now, this is not the case.

While I acknowledge this problem, it won't be of importance for 2019.3, neither will I have time or resources to fix this in the near future.

This could definitely could be improved, as @leonardder said it won't receive attention for 2019.3.
