The backspace button is sometimes deleting the character immediately ahead of the caret, instead of the character behind it. Other times, the backspace button functions fine, though I don't know which situations it works or doesn't work in.

For example, in [[VisualEditor:Test]], if one selects the place between the "n" and "l" in the word "only" on the third line and presses backspace, "oly" is displayed for a split second before changing to "ony".

Tested on Chrome/IE9/FF15 on Windows 7.
