It's inconsistent with how selections work on Mac. Open TextEdit, type in 
the string "aouiaoueioethaoieiaoe", press Command+F, type "tha", hit 
Enter, and check to see what direction the selection is. It's not a 
forward selection, it's a default non-directional selection.

IMHO anything in the DOM API that is defaulting newly created selections 
to "'forward' is buggy, since that doesn't match the platform.
