Under some circumstances, subgraph widgets in the properties panel would
have incorrect drag state
- Debouncing list state would cause a race condition where a double
click would initiate a drag on an element that no longer exists
- This is solved by removing the debounce.
- Right clicking on widgets would initiate a drag
- Dragging now explicity requires a primary button click.
Additionally, drag is now ended on `pointercancel`. This is purely for
safety and may not actually be required.

The third PR for managing display of widgets on subgraph nodes. This is
the one that actually makes the functionality usable and user visible.
Adds
- A right-side modal for configuring which widgets are promoted,
accessed by right click or selection toolbar
- This menu allows for re-arranging widget order by dragging and
dropping.
- Indicators inside the subgraph for which widgets have been promoted.
- Context menu options for promoting or demoting widget inside of a
subgraph.

Known issues
- Some preview widgets are not added to a node until a draw operation
occurs. The code does not yet have a way of determining which nodes
should have draw operations forced to facilitate initial widget
creation.
