Comment (by karsten):

 Hmmm. Can we first evaluate possible alternatives before editing libraries
 ourselves? For example:
  - Is there a way to redefine this function in our own JavaScript and have
 it override the one in Bootstrap? Sorry, if this is too naive.
  - Should we downgrade to 3.3.5? What possible downsides does that have?
  - Should we upgrade to 4.x? What can possibly go wrong?

 And if neither of these makes sense and we decide we need to make this
 change to the minimized JavaScript file, is there anything that we link
 where others have done the same thing before?
