If query-replacs goes into `intangible' sounds like a bug for me.
Whilst with `invisible' it seems reasonable. Emacs don't need eyes... :)
`intangible' is a new concept to me. For anyone else trying to follow along, intangible is documented in the Elisp manual (but not in Emacs' Concept Index which is the first place I looked).
One thing it mentions:
When the variable `inhibit-point-motion-hooks' is non-`nil', the
`intangible' property is ignored.
I assume that is not set but it might be.
From grep'ing the source and looking at what is in the Elisp manual and the comments in the code, I too would expect searches to not enter intangible areas. The code also mentioned "sticky forward" and "sticky backward" -- not sure what that is (yet) but that might be affecting things too.
