VoiceOver in Safari on macOS cannot interact with combobox

[olivvybee]

• downshift version: 6.0.6
• node version: 12.6.1
• npm (or yarn) version: 6.14.6

Relevant code or config

Issue can be seen in the useCombobox "basic usage" example in CodeSandbox: https://codesandbox.io/s/github/kentcdodds/downshift-examples?file=/src/hooks/useCombobox/basic-usage.js

What you did:

I am attempting to use useCombobox with VoiceOver on macOS in Safari.
I have tested using Safari 13 and Safari 14 on macOS 10.14 and 10.15.

What happened:

When navigating to the combobox with VoiceOver, it reads "You are currently on a pop-up combo box, inside web content. Type text or, to display a list of choices, press Control-Option-Space.". The issue is that neither typing or ctrl-opt-space do anything – text never appears in the input field and the list of options never appears. This prevents VoiceOver users from interacting with the combobox at all.

Problem description:

Comboboxes created with useCombobox are not usable with VoiceOver in Safari.

Suggested solution:

None

Through some testing, I found that if I remove the role="combobox" from the outer element (added by getComboboxProps()) then VoiceOver can interact with the element again. However, it no longer gets announced as a combobox. This is the workaround I'm currently using.

Hi @olivvysaur! Thank you for reporting this, I was hoping this use case will work. Is your scenario working in the examples from ARIA at https://www.w3.org/TR/wai-aria-practices/examples/combobox/aria1.1pattern/listbox-combo.html?

[olivvybee]

I see the same behaviour with those examples. I guess this might be a bug with VoiceOver or Safari.

[silviuaavram]

It may be worth looking at https://raw.githack.com/w3c/aria-practices/aria1.2-combobox-proposal/examples/combobox/combobox-autocomplete-list.html as well. ARIA are changing the DOM structure guidelines. Not sure when ARIA 1.2 will land, I believe they are currently in draft still, but downshift will support the new guidelines.

[olivvybee]

Hmm so in the 1.2 version interacting with the text field still does nothing, but if I activate the dropdown using the button next to the field, it works as expected (I can type and move up and down using the arrow keys).

[silviuaavram]

So it's still not the behaviour you are looking for. Follow up with ARIA or VoiceOver/Safari?

[olivvybee]

As I said I think it's a VO/Safari issue because it works fine in other browsers. It might be worth calling out in the downshift documentation until it gets fixed.

Feel free to open another issue if this persists in v7. Thanks!
