Properties tooltip and time slider behaviour

[kd-ods]

Bug description

When the time point changes, if a properties tooltip is open, it remains open and does not update.

Steps to reproduce

1. Paste this JSON into the visualiser tool and click 'Draw'.
2. Drag the timeslider handle to the 2020-09-11 point.
3. Click the 'Patrick O'Donohue' node. A tooltip pops up and the disclosure widget is populated and open.
4. Drag the timeslider handle one step to the right, to the 2021-09-11 point.
5. Notice that the disclosure widget is closed, but the tooltip remains in position and contains the content of the 'old' node.

Expected behaviour

Like the disclosure widget, the tooltip should disappear once the handle on the timeslider moves.

This should be straightforward to fix and is likely related to #178.
