When use the control panel to change the selected item from timeline about react-chrono HOT 2 OPEN

Hi! I tried the 2.4.0 version, but unfortunately the above mentioned bug was only partially fixed.

When I use the timeline or the next navigation buttons (first, previous, next, last), the index handling works fine. However, if I use "Play Slideshow", it still returns the wrong index for onItemSelected: 1 less than it should.

Another thing I noticed about the index handling is that if I change the contents of the "items", the timeline jumps back to the first item (this is fine). If I then use the navigation buttons to move the timeline, however, it does not move to the next item (idnex 1), but instead to the current item in the previous items collection.

For example:

• if the selected item idnex is 5 (I select the sixth item)
• I update the items collection
• the selected item becomes the first (index zero)
• press the "Next" button
• the timeline will jump to the seventh item (with index 6)
