AX: iOS VO announces incorrect number of tabs for accordion widgets marked with role="tab"

• Component: Accessibility
• Status: RESOLVED FIXED

[mpiotrowicz]

In all examples tested, iOS announces n+1 tabs for accordion widgets marked with role="tab". Suggest that this is a bug as the role="tab" is the suggested approach for accordion widgets. The following examples all show the same behavior on iOS VO but work correctly elsewhere (including VO on desktop Safari)

Steps to Reproduce:
1. Visit any of the following links with VO turned on in iOS Safari and navigate to accordion widget

Actual Results
VO announces "tab 1 of n+1" with n the number of visible tabs marked up in the accordion

Expected Result
VO announces "tab 1 of n" with n the number of visible tabs marked up in the accordion
