updateTile
Applies updateData as a shallow JSON-patch merge onto the tile identified by tileId — see dev.catbit.mosaic.client.ui.sdui.foundation.tiles.holder.tile.TileHolder.update for exactly how the merge (and the special handling of a "style" patch) works. The lookup also searches inside event holders' own nested tiles, not just the plain tile tree.
Parameters
tileId
id of the tile to patch.
updateData
the patch to merge onto that tile's current fields.
