Very much so.  If there is a category text property at some point, and
the symbol it uses has a foo property, that will normally get seen by
the text property primitives.  However, if you put a foo text property
there with a nil value, that nil value will mask the intent of the
category property.

It might be worth considering whether the new search function will take
account of category properties, and if so, how.
