guiText.HitTest(Input.mousePosition) is not triggering

I have a GUIText object that I cam trying to do some hover and click states for, but the Hit Test is not triggering.

By printing the guiText.GetScreenRect() I was able to find out that it has a height of zero, which would mean that the hitbox could never be hit.

 (left:363.50, top:38.00, width:77.00, height:0.00)

I have tried both with and without a collider attached with the same result.

Is this a bug in the hitbox calculation or am I just messing it up?

 if(guiText.HitTest(Input.mousePosition)){
     //do the things
 }
