RSRP-469389: typing escaped double quote consumes end quote

If I am typing a string, it will go something like this (pipe | character indicates cursor location):

1. Before typing first quote:

    var foo = |
   

2. After typing first quote (all is good so far);

    var foo = "|"
   

3. Go to insert an escaped quote:

    var foo = "\|"
   

4. Type the quote and the end-quote gets consumed. Note the cursor is now past the end-quote and I have to type another quote to actually close the quote and any typing assistance has been lost:

    var foo = "\"|
