play-stop dont work after zooming in timeline

When you zoom in or out the timeline using the bar at the bottom of the window, usually what you do next is to press spacebar to play, it wont play unless you click inside timeline to unselect the zooming bar.
It took me some hours to realize what was happening, it would be better if I can just press spacebar without needing to fist clic inside the timeline as it was always like this.
