Dead zone where a unit dies

I first noticed this a long time ago but have never posted about it or read anyone else posting about it. Please if you understand whats going on post a reply.

As far as I can tell on all maps and modes, when you are clicking on a unit and that unit dies, if you continually click on the same spot nothing will happen. I tested it earlier today and found that if I kept clicking I could just sit there for like a minute, until I gave up, not a single command getting through. If you click somewhere else it ends this and the area of the map becomes clickable again.

This is not a terrible thing but when it happens at the wrong moment it seems needlessly frustrating. I would love to hear others' opinions on this.
