[FIX] web_tour: toggle tip opening/closing in a more robust way
[FIX] web_tour: toggle tip opening/closing in a more robust way

A system was implemented to not close/open a tip if the user
leaves/enters the anchor and immediatly re-enters/re-leaves it but that
system was broken at some point.

This commit restores it.
