@tink In the expanded menu, there's a number of decorative images not hidden from assistive technology, and towards the end of the menu items, a horizontal separator line receives screen reader focus. Focus not trapped in the menu. In the main area, after the range, there's a mislabelled image of an arrow that's horizontal and points to the right side of the screen, possibly to communicate the trend of the current reading (?) and then there's an unlabelled button, its visual label is "Add note".
