Description
Some values for the props accessibilityRole and role have no effect on both iOS and Android platforms.
Meaning the screenreader doesn't read the role after the accessibilityLabel.

With no effect

[
'alert', 'combobox', 'menu', 'menubar', 'menuitem', 'radio', 'radiogroup', 'scrollbar', 'spinbutton', 'tab',
'tabbar', 'tablist', 'timer', 'list', 'toolbar',
]
On Android
[
'tabbar', // Throws error on Android
'search', 'keyboardkey',
]
With questionable effect
On iOS
[
'togglebutton', // Gets the Traits value: `Button`, while the 'switch` role gets 2 traits `Button` and `Toggle`. Shouldn't the role togglebutton have the same traits as the 'switch' role?
]
