Marcin, are you actually asking whether `help-echo' can or
should be used without font-lock? If so, the answer is YES.
Text properties (including `face' and even `font-lock-face',
BTW) have nothing, per se, to do with `font-lock-mode'.
Font-lock is only one user of text properties. Users and
code can use any properties in any way.
And property `help-echo', in particular, is used far and
wide outside of any use font-lock might make of it.
(As for the bug, I have nothing particular to say. And your
question about what breaks is reasonable. But keep in mind
that anything (font-lock or anything else) that assumes or
acts like it owns property `help-echo' is acting irresponsibly
and is bound to lead to bugs.)
