Editor middle click detects Event.current.button as both 0 and 2

Hi, in the following code in the editor:

Code (CSharp):

1.         if (nameRect.Contains(Event.current.mousePosition))
2.         {
3.  
4.             if (Event.current.button == 2)
5.             {
6.                 Debug.Log("pressed " + Event.current.button);
7.             }
8.             if (Event.current.button == 0)
9.             {
10.                 EditorGUIUtility.ShowObjectPicker<Object>(null, true, "", 3);
11.                 Debug.Log("pressed " + Event.current.button);
12.             }
13. }

It detects middle click first, but if I leave the mouse over the Rect, it then detects left click as well (which I never do, of course). I could not find any info on similar problems online, does anyone know what can be happening here? Thanks in advance!

 

OK, so I found a solution accidentally. I do not understand why it works the way it does, but I'd be happy if someone explained. Here's the code that now works as intended:

Code (CSharp):

1.         Event e = Event.current;
2.         if (e.button == 0 && e.isMouse)
3.         {
4.             Debug.Log("pressed " + e.button);
5.         }
6.         else if (e.button == 1)
7.         {
8.             EditorGUIUtility.ShowObjectPicker<Object>(null, true, "", 3);
9.             Debug.Log("pressed " + e.button);
10.         }

First, it won't work properly if you don't use Event e = Event.current;
Second, it won't work properly if you don't check e.isMouse
Finally, it won't work properly if you first check e.button == 1 and then e.button == 0, like so:

Code (CSharp):

1.         Event e = Event.current;
2.         if (e.button == 1 && e.isMouse)
3.         {
4.             Debug.Log("pressed " + e.button);
5.         }
6.         else if (e.button == 0)
7.         {
8.             EditorGUIUtility.ShowObjectPicker<Object>(null, true, "", 3);
9.             Debug.Log("pressed " + e.button);
10.         }

I have no idea what's going on here...
