Isn't 100 too short a timeout? Make it 1000 to accommodate everyone?

You only need it to hover over the popover.

The "showPopover" timeout is set to zero, which means you get this popover
instantly as you hover over the link. The 1000 will make them "stick" - and it
doesn't feel good, given you hover over links
accidentally 90% of the time.
