**Short description of error**
When having only one keyframe in dopesheet, by pressing Home key, it makes a strange zoom. The keyframe diamonds dissapear. Like this:
To see again the diamonds, you have to middle click the mouse and move. Then, they appear at a very zoom-in.
If you move the mouse wheel after pressing Home key, the vertical lines and horizontal channels are gone and all the area is only gray. As you can see in this image:
**Exact steps for others to reproduce the error**
Open the file.
Press Home key in DopeSheet area.
Click middle mouse button and move
Pres Home again.
Move the mouse wheel.
**What I think it should do**
When only one keyframe is there, the home key should zoom in to (maybe) 10 frames long. If there are 2 keyframes, the zoom area would be that 2 frames long.
