    # Rationale for this change
   This PR adds an initially failing test in 
a060b40f14f6a28945d0e15c2ae893136a9d55b9 that reproduces the behavior described 
in #1411.
   
   The change in 2042fbb8e16cd5908563c0f8faafe000f02ec029 may not be correct 
overall, but it addresses this particular failure.
   
   The core issue seems to be that filter optimization examines fields across 
all plans and then fails because there is an ambiguity. At least in the 
DataFrame context, I would expect there to be no ambiguity since only one of 
the columns is projected prior to filtering.
