Literal string quote bug is back

Using the 5.0 beta release (from December), I noticed an issue that was fixed in 4.x is back in 5.x...

Declare a literal string by typing:

private string foo = @"|"

Note the cursor is where the | character is, and the closing quote was auto-inserted.  Now, if you type a quote character, instead of over-typing the auto-added quote, it inserts a new quote, resulting in this:

private string foo = @""|"

(where | indicates where the cursor is).

Just FYI.
