Tested manually basic DnD and Grid DnD on Mac with Chrome, Firefox, Safari.
Safari is still missing drag image (regression).
Tested manually basic DnD and Grid Dnd on Windows IE11 and Edge.
Drop event for both is still not working properly #9174.
This patch introduces a Tree component, implemented as a Composite
using TreeGrid. As initial version of the component, some functionality
of the old Tree component has been left out for now.
Partly addresses #8617
Improve expand and collapse of items in TreeGrid (#9159)
Fixes a race condition when expanding multiple items.
Only one expand or collapse request should be sent from
the client before waiting for a response, otherwise the
indexing in subsequent requests will be incorrect.
Adds API to collapse and expand multiple items from the
server, reducing the amount of round trips with multiple
item expands and collapses.
HierarchyMapper now correctly keeps expanded nodes expanded
if their parent is collapsed.
A composite is included in the server side hierarchy and in the connector
hierarchy on the client side but does not have its own widget or DOM.
To ensure that captions etc are renderer correctly for the root contents,
the client side connector returns both the widget and state for the content
connector.
Server side API related to width and height are automatically forwarded to
the root component to enable easy use of the composite inside different
layout configurations.
Other server side API inherited from AbstractComponent is unwanted, should be
optional and therefore throw an exception by default.
Resolves #2458
