lpDirectory must have priority in ShellExecuteEx

For example, there are two files with the same name: sample.txt

First file placed to:
C:\sample.txt

Second file placed to:
C:\ReactOS\sample.txt (C:\Windows\sample.txt - for windows)

I use ShellExecuteEx with this parameters:

lpFile=sample.txt
lpDirectory=C:\

Windows result:
Opens: C:\sample.txt

ROS result:
Opens: C:\ReactOS\sample.txt

If "C:\ReactOS\sample.txt" not exist then ROS open "C:\sample.txt".

This is the wrong file search order. ShellExecuteEx must first perform a search in lpDirectory if specified.
