IDE: wrong search-order for duplicate unit

Description:

Wrong search-order in a project which contains duplicate unitnames:
The IDE has a different search-order for unit than the compiler.

Compiler search-order is:
Projectfolder unit (eg. bugfixed unit) overrules units of other folders.

Example of project structure:
project\mainUnit.pas // contains "uses myUnit": IDE/FPC search in projectfolder
project\myUnit.pas // bugfixed version
project\shared\myOpenUnit.pas // contains "uses myUnit": FPC searches in projectfolder, IDE searches in sharedfolder
project\shared\myUnit.pas // original version

1. In IDE, open a unit (mainUnit or myOpenUnit) which contains the text "uses myUnit".
   
2. IDE command "Find declaration of myUnit" should open the used "myUnit".
   
3. Wrong behavior: IDE searches at first in the folder of the open unit.
   Correct would be: IDE searches at first in the projectfolder.
