From what I read, they call that a "nuisance alarm"* and many people purposely disable their detectors (similarly to what I did that night, but more permanently) when it happens a lot.
So the companies have designed them to give fewer false alarms. But also, the ionization type is more likely to have those kind of false alarms than the photoelectric, so maybe your new one is photoelectric.

*I mean, unless your toast actually tends to catch flame.

This page has pretty good info about a third of the way down the page, about photoelectric vs ionization:
