#4690: Line Clipping MVT failure?

Comment (by Algunenano):

 A couple of notes:
 - Line clipping uses GEOS in all versions; wagyu is only used for polygons
 in 3.0+
 - It seems like the issue is found in lwgeom_clip_by_rect, so the first
 thing I would do is to extract the offending geometry and the the clipping
 values (those we can already see in the callstack) to try to see what's
 going on in there.
