Yeah, this ligature struck me as intentionally ironic.
Look at it's design: it's an entirely unnecessary loop that goes way up out of the way of the bits that are supposed to be connected and makes a sharp turn. Opposite to the actual function of a ligature, which is to correct a visual quirk of juxtaposing two letters, it goes out of its way to introduce a visual quirk.
So, it's not so much a "bad" ligature as it is a caricature of one.
