[orca-list] Your thoughts on item position and count in menus?

[Joanmarie Diggs <jdiggs igalia com>]

Hey all.

Consider the following menu (it's Thunderbird's Help menu)

Help Contents
Troubleshooting Information
Release Notes
Restart with Add-ons Disabled
About Thunderbird

There are five items, and Orca currently presents their position and
count (for those of you who have that option enabled) as:

Help Contents. 1 of 5
Troubleshooting Information. 2 of 5
Release Notes. 3 of 5
Restart with Add-ons Disabled. 4 of 5
About Thunderbird. 5 of 5

I assume you all agree that this is correct, given the information I
have provided. But it turns out this menu has non-navigable separators
in them. What I see on screen is:

Help Contents
Troubleshooting Information
Release Notes
<separator>
Restart with Add-ons Disabled
<separator>
About Thunderbird

Each separator appears as a low-contrast, thin, but still visible
divider which visually groups things. With this information in mind, is
what Orca presents currently correct? Or should Orca instead say:

Help Contents. 1 of 3
Troubleshooting Information. 2 of 3
Release Notes. 3 of 3
Restart with Add-ons Disabled. 1 of 1
About Thunderbird. 1 of 1

Please let me know what you think. Thanks!
