Syntax highlighter correctly 'bolds' the name of a property, if it detects it's a function (and not otherwise):

x = {
 onChange: function(params) { ... }
};

It incorrectly bolds it when the name of the property is quoted:

x = {
 'onChange': function(params) { ... }
};

It bolds the correct number of characters, but starts at the first quote mark (offset left 1 character), which leaves
the last character of the name, and the ending quote mark, un-bolded.
