`TreeView` supports showing a node without selecting it

[metonym]

TreeView currently supports "showing" a node.

However, it "selects" it by default. I would like to show the node without selecting it.

• Should selection be the default?

Great function that i could use as well. Maybe this would be a good default:

• when clicking the twisty it expands the node but does not select it
• when clicking the label it exoands the node and selects is.

Additionally, maybe an option to leave other branches expanded when selecting a node. Currently showNode() expands up to the selected node and closes what was already open.

Here's what i use for that:

/** Expand the selected node, and leaves previously opened nodes open */
	function showMultipleNodes() {
		if (items.selectedIndex && items.currentItem !== undefined) {
			addParents(items.currentItem);
			expandedIds = [...new Set(expandedIds)]; // remove duplicates

			function addParents(item: Item) {
				const parent = items.list[items.getIndex(item.parentId)];
				if (parent) {
					// console.log(`Parent of ${item.name} is ${parent.name}`);
					expandedIds = [...expandedIds, parent.uuid];
					addParents(parent);
				}
			}
		}
		refToTree?.expandNodes((node) => {
			return expandedIds.includes(node.id);
		});
	}

Thanks for the feedback!
