Bug 155613 – AX: Typing broken on form input field while using VoiceOver

• Component: Accessibility
• Status: RESOLVED FIXED

[Nan Wang]

When navigating to the form elements with VO + the arrow keys and then stopping at a input field, the cursor jumps and there's no way to type.

Spent quite a long time trying to figure out a way to test. Was adding the AXSelectedTextMarkerRange notification to the test and getting the TextMarkerRange when input field is focused. But even we get the TextMarkerRange for that selection, it's difficult to determine which node the TextMarker is associated with. Or we can expose some function to get the Range object from TextMarkerRange, then check the node in it. Seems there's no easy way to do this. So I'd rather put the fix here first.

it seems like we could write a test with "a <div contenteditable="true"></div> b" and get the range of the whole content there and then verify that the length is correct or that it has the right embedded elements

why does this break typing with VO?

I think VO is asking for a textMarkerRange of the input field, without this fix the contenteditable div is not included in the range. So VO had no idea what's inside the input field.
