Switching tabs 'synchronizes' all clocks on the page #2
Description
Not really an issue, more or a very minor annoyance but wanted to make sure you know it's there so you can check if it could lead to some other problems along the way :)
Go to the demo page and start time timer and/or countdown but make sure to start it in a way that is not 'synchronized' with the top clock (with this I mean that the seconds aren't ticket at exactly the same time). Now switch to another tab and back, now all clocks are 'synchronized' (ticking at the same time).
If you combine this with #1 (first make a timer faster then switch tabs) you can see the 'sped up' timer jump multiple seconds in one 'tick'.
