Very easy to explain. When I want to delete a file, I pressed the right button, then in the menu i select the trash option. Usually, if I press the mayus key, the option changes to delete. But here it doesn't change. It will change when I release the key, and have to press it again to send to trash again.
It's working the opposite way it should.

Reproducible: Always

Steps to Reproduce:
1. Open dolphin
2. Right click in a file or directory
3. Press the mayus key
4. Release the mayus key

Actual Results:  
The behaviour has changed to delete without mayus key pressed, and to send to trash with the mayus key pressed.

Expected Results:  
Opposite. Mayus pressed to delete, and mayus released to send to trash.
