Can you give a pointer to the Microsoft documentation which says that,
and/or documentation that explains how the LWIN-r combo works in terms
of Win32 API calls, and why it bypasses the normal keyboard reading
Emacs uses?

I'm well aware of your patched version.  The fact is, however, that we
do seem to have code in w32fns.c that tries to work around the Run
dialog being popped.  I asked my question (above) to try to understand
whether that code works at all, on any Windows system.  Presumably, it
worked for someone at some point in the past, or else it would not
have been added to Emacs.
