“Can’t add the same components multiple times” pop-up appears when adding Component via Search window using Enter key

Reproduction steps:
1. Create a new project
2. Create any GameObject (e.g. GameObject > Create Empty)
3. Select created GameObject and open the Search window (Window > Search > New Window)
4. Enter “component” into the search field
5. Make sure GameObject is still selected and select any Search window result (e.g. Animation or Animator)
6. Press the Enter key to add the Component to the GameObject

Actual result: “Can't add the same component multiple times!” pop-up appears and the Component is added only after pressing “Cancel” button
Expected result: Component is added to the GameObject
