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.
