Why does Safari display the letter combination ‘fi’ as ‘if’

... climaxing in a telegenic finish ...

Neither does Google Chrome:

Can anyone explain this behaviour?


System:
MacBook Air (MacBookAir3,1)
Intel Core 2 Duo; 1,6 GHz

Safari Version 9.0.2 (11601.3.9)

It's an official bug, yes. It seems to be solely happening with Merriweather Sans.

Maybe someone at Apple or on the east coast decided to protest the name of the font? ;)

Seriously, an update is in the works, and someone here suggests a work-around.
