It looks like the setting can be changed if there are no other tabs open, and it fails to change (either to on or to off) if another tab is open. E.g. step 1 above.

Working hypothesis: The Launch button triggers an additional click on the toggle, reversing the current setting. If there is only one tab open the shutdown happens quickly enough that the second toggle is not registered (thrown out in transit). If there are multiple tabs open, the shutdown takes long enough for the second click toggle to get through and reverse the toggle state. Commenting out the relaunch code shows that the Launch button is generating a toggle state change.

[MD settings] remove action-target on settings-toggle-buttons

This CL removes the action-target method of setting tap targets for toggle-buttons. 
To make the settings-toggle-buttons whole row tap/clickable, the extraneous outer 
<div> is removed.

This also includes a fix for the Launch button that appears within the toggle-button to user hardware acceleration.
