Material-components-android: [NavigationView] Talkback does not announce the number of items in the NavigationView

[sixpi]

Description: Talkback does not behave as expected on the navigation drawer - it is including separators between menu item groups in the count of items in the list of items in the navigation drawer. Additionally, the header view automatically adds 1 to the count of items, even if it has no focusable items or if it has more than 1 focusable items.

Expected behavior:

I would expect talkback to announce the total number of focusable elements in the navigation drawer, regardless of whether they are menu items or children of the header view(s) (and I suppose footer views as well). I would not expect any automatically inserted separators between menu item groups to be counted.

Source code:

Minimal sample which adds a navigation drawer with 2 groups and a header containing 3 items is attached. The app will announce 7 items instead of 8 items. Additionally, if android:focusable="true" is removed from the items in menu_header.xml, then the entire header view is focusable.

So we looked into this on 1.0.0-beta02 and we no longer announce any item counts. I'm updating the issue to reflect this.

Version 1.0.0: Incorrect numbers
Version 1.1.0-beta02: No number
