I think this is expected behaviour.
As alluded to in comment #3, the border "islands" in the screenshot (global observer view) correspond to territory the Danes know.
Normally you claim otherwise unclaimed land up to a certain radius around border sources such as cities, but you can't claim land you've never seen, so the "unknown" tiles are punching holes in those circles.
The end result of non-contiguous borders is a bit odd. Ensuring contiguous borders in this case would require quite a different borders algorithm to what we have in map_claim_border() today.

Game was started with one human player attached to the Saxons. After a few turns I aitoggled the Saxons, turned on a timeout, and became global observer.

This seems to be connected to the 'known' state of the tiles. If you enter the edit mode, add some explorer in the known territorium of the Danish and go into the unknown area they will be marked as Danish.

How did you start this game? It is not a autogame as minplayer is set to 1?

This was a game started from scratch.

Check the Danish borders in this savegame.

Do you started the game or loaded? Could you attach a savegame?

In a recent S2_3 small unconnected pieces of border "islands" appear sometimes.
