Yeah, we have the recent proposed fix for Customize buffers where
symbols like `fill-column' have a bunch of display properties put on top
that makes it look like "Fill Column"...  having isearch skip past all
that would be unintended.

I think perhaps the most obvious and flexible is to just make isearch
work the way it does today on text with a display property (i.e.,
agnostic), and then have a standard text property that modes can use to
make isearch skip.  I.e., just having a replacing display property in
itself isn't a strong enough hint that isearch should ignore the text.
