When I specify dipslay: none or hidden="true" on binded element before document
load then constructor will not be called. Nevertheless binding is making i.e. i
can use it properties, methods.
Ok. Let constructor isn't called when element isn't displayed. But constructor
should be called when i'll remove property display: none.

Related like a duplicate, probably... not marking so since this bug has better
information, clearer testcases, and is in the right component....

That said, a usable testcase (one that points at the CSS and XBL in bugzilla)
would be nice (in general, attaching the auxiliary files first and then
attaching the main testcase pointing at them is the way to go).

(or a single file with embedded XBL)

Like several other bugs, I think this one is mis-summarized. display: none
elements shouldn't have an XBL binding applied at all. We already do this
correctly for <b> below, because b doesn't have a style context. <a> however,
gets the binding applied, which is almost certainly "incorrect", by some
definition of incorrect:

<a style="display:none; -moz-binding: url(foo2)">
  <b style="-moz-binding: url(#foo2)" />
</a>

If you really want <a> to have an XBL binding, it should be visibility:
collapse; instead, which should work correctly with <constructor>s and such.

I agree (or understand) element shouldn't have binding at all when it have 
style display:none. However, such element have binding but it is unimportant. 
The bug lies in constructor will not be called if style dipslay:none of element 
will be changed.

now binding is applied even if attribute 'hidden' or style 'display:none' is setted.

Unless you can point out which bug FIXED this, and you should when you mark it
so, this should be WORKSFORME or stay open.
