SUMMARY
When editing the Location/URL Bar present in Dolphin, pressing Enter/Return or using the checkmark icon to exit the state returns the full path. 

Canceling the edit with the Escape key truncates the path to only show the current directory, until clicked into and then "Saved" with Enter.

STEPS TO REPRODUCE
1. Open Dolphin and navigate to any folder two or three levels down
2. Click into the URL/Location bar to edit, then immediately apply the change with the Enter/Return key
3. Click into edit mode again, but this time exit using Escape key

OBSERVED RESULT
The displayed path truncates to only show the current directory when exiting edit mode with Escape. Exiting with Return or mouse click displays the full path properly. 

EXPECTED RESULT
The path should fully resolve in all cases. 

SOFTWARE/OS VERSIONS

KDE Frameworks Version: 6.12.0
Qt Version: 6.8.0

ADDITIONAL INFORMATION

Not sure precisely how old this bug is (unrelated to recent styling changes in frameworks 6.12). 

I believe this is due to Key_Escape not being defined as a mapped option in `KUrlNavigatorButton::keyPressEvent`. 
A preliminary test didn't alter the behavior though.
