Changed TileIds after drag

[tosti007]

When inserting a new Pane into Tiles, it returns a new TileId. The behavior I'd expect is for this TileId to consistently refer to the same Pane throughout the lifetime of the Tree.

However, this seems this is not the case; when a e.g. Tabs container with two Panes is changed into a Horizontal Container, my first Pane's TileId refers to the Horitonzal Container in which the Pane's TileId is stored.

Would it be possible to keep current TileIds always refer to the same Tile? Not only would this remove the need to manually keep track of which CustomId belongs to which Pane, it would also fit (atleast in my opinion) the mental model of a TileId better.

I'm also fine with implementing it myself and saw the insert function, but I'm unsure whether that's the correct place, so would like some small pointers for it.

Thanks!
