Play button does not work if switching slides when play is going

When there is multiple slides like 2-3 and user press play button on one of those and just click to other slide -> Play is stopped and play button does not react. Timeline play works again if user press first stop and then play. This might be a bit confusing for user because Stop button is deselected even its "on" at background.

1. Create few slides
2. Add something to slides
3. Press play on Slide 1 
4. Go to Slide 2 and press play

       -> Nothing happens and stop button is deselected.
