Should we use mergeSlotProps here?

[siriwatknp]

mergeSlotProps does not concat event handlers, if users provide onEntering it will replace the handleEntering of the Menu. That's why we need to check for typeof function here so that we can:

  onEntering: (...args) => {
    handleEntering(...args); // menu logic
    resolvedTransitionProps?.onEntering?.(...args); // user logic
  },

I don't want to go that far to make mergeSlotProps handle event handlers concatenation because it might effect the performance because the logic will need to loop all slotProps to identify which prop is an event handler (starting with on*).

[siriwatknp]

No because it will produce a different behavior. The reason to check for typeof function is to use the ownerState of the Menu, not the Popover.

Same reason as the above comment.
