PR# 17671 Violation of precondition `a_split_position_within_bounds' of {SD_VERTICAL_SPLIT_AREA}.set_split_pos

While opening a saved layout in a workbench estudio, I got a precondition
violation with tag a_split_position_within_bounds in
SD_VERTICAL_SPLIT_AREA}.set_split_position.  Not reproducible at this time,
but perhaps you can tell what is wrong from the trace.  Full trace attached.

I tried opening the same saved layout again, but there was no assertion
violation.  I may have been resizing the main window while the open was
in progress.

Not currently reproducible.

This is now reproducible.  To reproduce:

Start workbench estudio with preconditions enabled and open existing project.
Select View/Tools Layout/Reset Tools Layout to get default layout.
Arrange tools to look like the attached screenshot.
Resize main window as small as possible (as narrow and as short as possible).
Select Execution/Force Execution Mode.
Estudio crashes with precondition violation.

I got this one again, this time while switching to Force Debug Mode.
The main window was resized very small.

In the debugger, `a_split_position' had value 61, while
`minimum_split_position' and `maximum_split_position' both had value 60,
so `a_split_position' was not between minimum and maximum.

Stack trace attached, in case it is different than the first one.
