Update Code to 1.83.1 (#6488)

* Update Code to 1.83.1

* Patch out lookbehind for Safari support

Not sure why it needs a lookbehind unless a number followed by a capital
letter is not supposed to be considered a new word, which seems wrong to
me.  The tests do not contain any numbers so I can only guess.
