Bootstrap/js/button.js
Chris Rebert e67e3e9b19 button.js: Set disabled property in addition to disabled attribute to preserve behavior under jQuery 3 (#20278)
This code ought to have used .prop instead of .attr in the first place,
but we can't get rid of the attr manipulation now due to backward compatibility constraints.
