History gets messed up when paging too quickly

[dylanmorroll]

One of my favourite features of this extension is being able to see repeated visits. I often use my browser history to figure out what I was doing on certain dates, which is impossible when half the entries are missing.

However, the history isn't correct sometimes. If I go to the month view, and scroll back a few months, everything looks fine at first. If I click on a specific date, still everything looks fine. Then, after a few seconds, the history starts jumping (the whole list changes, presumably it's somehow loading the history of a different day). Sometimes if I navigate to the previous day and forward again, it sorts itself out. Other times, it's a whole new set of history again (yet another day of history).

If I navigate slowly through the months when going back (i.e. I let each month load, before navigating to the next), then it appears to work correctly. But if I page through the months without letting them load, it starts getting weird.

Apart from that, love the extension! Thanks for the hard work :)
