bug: v5 Accordion component issue on IOS

[nurm717123]

Describe the bug
I've tried to use the new v5 Accordion component and noticed additional left triangle icon, and the right arrow always showing collapsed state despite the accordion already expanded

Expected behaviour
the left triangle icon to not shown, and the button-icon to show expand/collapse state correctly

Screenshots

Additional context

tested on IOS Chrome & Safari 15

@nurm717123 This should be fixed now, though please not my PR comment regarding the user-agent's disclosure marker. Generally speaking, we're not going go to much effort to support old browsers like Safari 15.
