Switch at Clone container doesn't contain documentation

I just wanted to clone a container and found out that at the corresponding page, there's a switch(ON/OFF) button that's undocumented.
The DOM contains traces of what probably should've been there:
data-on-label="<small>Snapshot</small>" data-off-label="<small>&nbsp;&nbsp;&nbsp;Classic&nbsp;&nbsp;&nbsp;</small>"

Below is the code actually being ran:
<span class="switch-left">ON</span><label>&nbsp;</label><span class="switch-right">OFF</span>
