Accessibility: Screen readers are not aware of autocomplete suggestions for / and action list

[zersiax]

Pretty much as it says on the tin. No ARIA markup is present to make sure screen reader users are aware what autocomplete suggestion is in focus. Most of the ret works fine, but that bit appears to be broken which is unfortunate.
Could this be looked into, so companies that want to adopt this for their on-premise note taking tools won't have to severely inconvenience or outright fire their screenreader-using employees? Thanks much! :)
I'd be happy to answer questions if there are any.
