Minor Changes

• 21d1679: add canDragForeignDragObjectOver to allow customizing whether a draggable visualization should be shown when dragging foreign data. This allows differentiating logic between drag-over and drop (via the existing canDropForeignDataObject), since for the latter dataTransfer.getData is not available by default in browsers.

Patch Changes

• e8ddbb0: Added item.updateCachedData(data) in async tree feature, that works similar to the existing item.updateCachedChildrenIds(childrenIds) feature
• 662e2a8: Added stories and documentation on how to use nested DOM rendering for tree structures instead of flat lists,
  which can be used for animating expand/collapse behavior
• b41e1d2: fixed a bug where ending drag without successful drop doesn't properly reset drag line (#132)
• b413f74: Fix aria-posinset and aria-level to be 1-based indexing
• a250b3b: Fix a bug where expand from the initial keyboard focus fails when rootItemId is an empty string
• 62867e8: Introduced a short delay before hiding the drag line when leaving a drag target, which helps to reduce flickering of the dragline when moving between items
• c4579eb: Update keyboard drag and drop to include the focused item in the dragged items
• 662e2a8: Improved customizability of checkboxes feature (still alpha state), allowing you to customize propagateCheckedState and canCheckFolders independently
• 662e2a8: Changed to new buildtool in core packages (now using tsup) to hopefully fix some ESM/CJS integrations
