They're currently enabled on page load. Even when dismissing the notice and clicking around in the first paragraph it stays.
It finally disables itself after a node change (e.g. click the second paragraph and then back).

From conversation earlier today:
It may be possible to hack the button to be disabled by default, but that would introduce the opposite bug where the indention tool would be disabled instead of enabled in a document that starts with a list, requiring the user to move out of the list and back in to be able to indent.
Basically we should make sure that our hooks that make the button enabled/disabled on node focus change also trigger when initially focussing the first node in the document (instead of only from the second node focus onwards).

Init surface after toolbar is setup vs. before.
