Someone above said it, drag.

A faster tyre isn't faster, it just suffers less losses.

A faster tyre isn't necessarily faster (insert note), it will just slow down more slowly maintaining what effort you put in for a longer amount of time.

Note -though when you're accelerating it there are less losses the whole bike will end up a bit faster, just just the one wheel, it's all connected together, if you wanted to be pedantic the rear wheel will be pushing the bike forward as it were

It's because the bike is rear wheel drive. If you move the chain to the front wheel, you'll need the fastest tyre on there. Look at dragsters. Slick tyre on the drive wheels, every time.

Because this is what happens when you put the faster rolling tyre on the front.

If you put a faster rolling tyre on the back, what happens is, as the back is goes faster, it overtakes the front, and then becomes the front, so you end up riding backwards down the trail. As the back (which was the front) is going slower than the front (which was the back) the front accelerates away, stretching the bike, which then means you can't get round the next switchback and the bike gets stuck.
Or something like that.
Go round your local trails on a Sunday and you'll see lots of elongated bikes stuck between the trees at sharp corners with bemused-looking riders scratching their heads...

Surely the bike will only roll at the speed of the fastest tyre or am I missing something?

well done. you have brightened up my afternoon!
