Fix T100841: Creating a frame node with shortcut doesn't sort nodes

Before 58c650a44c25, the nodes span was rebuilt on every redraw. Now
that it's only rebuilt as necessary, we need to tag it dirty when nodes
are reordered. Relying on the order of the nodes at all isn't ideal, but
it's fairly fundamental in many areas at the moment.
