Docked TextEdit Dragged Text Trick

Smoking Apples:

You can even spring load applications. For instance, if you want to drag in some text in TextEdit, just hover over the icon in the Dock and press the spacebar. Once a new window opens, drop in your text.

Nothing new (but much useful) in the rest of the article, but the snippet above surprised me. Why doesn’t text dragged onto a docked TextEdit icon open a new TE window pre-populated with the text? This is an annoying oversight by the OS X team. I’m grateful for this usable alternative method.
