[Reg : 5.10.1-> 5.11.0]QDir().absoluteFilePath() no longer recognizes resources

There appears to be a regression issue with recognizing resource path names, in Qt5.10.1, the code: QDir().absoluteFilePath(":/abc.txt") would return ":/abc.txt".
However, in Qt5.11.0 the string is expanded to something like:
"C:/Tickets/build-AbsolutePathIssue-Desktop_Qt_5_11_0_MSVC2017_64bit4-Debug/:/abc.txt"

Steps to Reproduce:

1. Run the attached project on Qt 5.11.0

Expected Result:

The output should be - ":/abc.txt"

Actual result: 

"C:/Tickets/build-AbsolutePathIssue-Desktop_Qt_5_11_0_MSVC2017_64bit4-Debug/:/abc.txt"

This is working fine in Qt 5.10.1
