steps to reproduce:

• load data:text/html,<input list="datalist"><datalist id="datalist"><option>a</option><option>bobo</option></datalist>
• open browser toolbox, switch to a11y panel, find grouping -> combobox_role correspnding to datalist popup (panel#PopupAutocomplete element)
• click at input to open datalist popup

child count in accessibility panel is updated, but the tree is not, which means the problem it not on a11y side (event_reorder is fired), but a11y tools doesn't respond it properly.

Yura, asked me to assign this bug to him, can't resist it :)

Thank you for the report.

I am trying to follow your STRs, but I don't understand what "grouping" is.
Can you provide more details about what this issue is about, thank you!

Accessible tree apparently has changed. Now it is:
document
editcombobox

If you click an input, then the tree is not updated. I'm not sure whether this is the same issue or whether this is a bug at all or not (for example, if a popup tree belongs to a different process), but it's better to check with Yura: a11y architecture might have changed dramatically from last time I looked.

Yura, you now have -1 ni? I believe!
