Here is a Google Street View from before bicycle markings were painted:
Portland, yet! Well, Portlandia.
Often, flubs like this result from a construction crew’s having its own ideas about design, as in “oh, there’s a ramp from the sidewalk and my 5 year old rides on the sidewalk.” I don’t think that you would find this in the design drawings. Portland traffic engineering has its ideas about bicycle facilities which I may or may not agree with, but leading a bike lane extension into the curb when there is a shared-lane marking in the next block isn’t one, or at least that seems very improbable to me.
it is distressing that this happened, and that the city didn’t immediately correct it.
