Jensen intervened once more to palm away a cross-shot from Porter and Michael Smith's follow-up was blocked.
Ross Warner made a great one-handed save to keep out a Hylton header but he was soon beaten.
Chris Sedgwick danced through two challenges to deliver a floated cross and Hylton found the net with a looping header in the 35th minute.
Michael Smith then spurned a couple of opportunities, finding the side-netting with one and firing another tame effort straight at Jensen.
But the visitors finally equalised when Moore picked up a Smith flick-on to thump a shot past Jensen in the 66th minute.
Neither team were able to clinch a winner with Dons substitute Jim Fenlon flashing an injury-time effort just wide.
