Bug 201840 – AX: USER: VO: Messages > Message > Shift-VO-M doesn't reveal correct actions

• Component: Accessibility
• Status: RESOLVED FIXED

[Eric Liang]

Seed user reports that in Messages, when VO cursor is focused on a message, Shift-VO-M doesn’t reveal the Tapback command (or other commands) user is presented with when they Control Click on a Message.

https://sitewatch.apple.com/watches/acker-public-seed/issues/342853

Steps To Reproduce:
1. Enable VoiceOver
2. Messages > focus VO cursor on a Message > Shift-VO-M > control click on message > control click outside of message

Results:
Shift-VO-M: only delivers ‘Clear Chat Transcript’ command. User expected Tapback command.

Regression:
Reproduced in 16C27

Notes:
What’s interesting is that the ‘Clear Chat Transcript’ command appears when Control-Click outside of message. This seems to indicate some weirdness with the focus, however, interacting with text of message doesn’t address the behavior.

can you use ascii characters here instead of unicode

> Source/WebCore/accessibility/mac/WebAccessibilityObjectWrapperMac.mm:3767
> +                ScrollView *scrollView = downcast<AccessibilityScrollView>(*parent).scrollView();

can you change this to 

auto scrollView while we're here. should probably also do

// just to ensure we have a scrollView
if (auto scrollView = ...) {

}
