Comment (by herrvigg):

 I'm recopying here what I wrote in other tickets. Not sure but this could
 explain the problem, asynchronous firing with jQuery3:
 https://github.com/jquery/jquery/issues/3194

 With jQuery3, `ready` handlers fire asynchronously and may be fired after
 `load`... there's no guarantee so that can explain some "random"
 behaviors.

 Long story short, the `load` trigger should never be set in the `ready`
 callback but outside. Ideally it should even be avoided when using
 `ready`.
