The type of window used is irrelevant. To pick just three examples,
HTML5 applications will not be able to avoid that on some platforms
there will be a menu bar, they will not be able to control their
taskbar/Dock icon, and they will not be able to handle documents
dragged to the application's icon. None of those have anything to do
with the type of window.

That doesn't make sense on those platforms where applications have menu
bars but windows do not.

IMO allowing "user agent vendors to create their own solutions" is a
copout from admitting that there is no practical solution for the
platforms some user agents are running on, which is bad for
interoperability. (For an example of such silliness, see
<http://www.w3.org/TR/2003/CR-css3-color-20030514/#flavor>.) There's no
point in providing freedom to choose, if the number of practical
choices is zero.

I don't remember anyone on this list suggesting that. Hiding them in a
menu would certainly fail my "reliably noticable" criterion

Sure, just as CSS can be used to alter the orientation of OL or UL or

No, because that would (on some platforms) still involve having two or
more visually similar menu bars on the screen simultaneously.

No, they'd do it "by using adjacent <menu>s, without a <menulist>
element". For example, <menu...>...</menu> <menu...>...</menu>.

I don't know what you're trying to say here.

How strongly the Web Apps spec suggests particular visual presentation
is suggested for <menu> probably depends on how strongly the What-WG
specs suggest particular visual presentation for controls in general. I
don't think Ian has said anything about that yet.

That would be even worse, but in a different way: it would mean in some
cases the current selection wasn't visible at all even immediately
after the menu was opened. For example, someone who chose "Uzbekistan"
by mistake instead of "USA" would have to scroll through (nearly) the
whole damn menu of countries again, instead of mousing down on the menu
and dragging northward ~5 pixels. (On the Windows platform, and in
Gecko on all platforms, decrementing a <select> value is more
time-consuming -- you need to click the menu, then move down(!) to
click the up arrow, then move across to click the correct item. But
that's still not as bad as a pull-down menu would be.)
That's probably why no toolkit I know of presents any of its
one-of-many selection controls (listboxes, scrolling listboxes, option
menus, or sets of radiobuttons) in the way the W3C illustrates. It
would be far too annoying.

Sure, but that's not what was being discussed.

As I said, "the distinction could not be shown in a single
native-looking option menu while the menu was closed, without making
the menu abnormally wide". The W3C's example uses abnormally short
submenu items in an attempt to make <optgroup> look practically
