Unable to reproduce the issue on mac 10.13.3 using chrome reported version #66.0.3355.0.

Attached a screen cast for reference.

Following are the steps followed to reproduce the issue.
------------
1. Opened a Google Doc while using VoiceOer.
2. Pressed Option + / to search the menus and typed a search value.
3. Observed that search results are spoken and it is possible to review or make a selection using the screen reader.

mjanusauskas@ - Could you please check the issue on latest canary #66.0.3356.0 by creating a new profile without any apps and extensions and please let us know if the issue still persist or not.

Thanks...!!

Re #2, I didn't hear search results being spoken in that video, or any attempt to select them.

mjanusauskas@afb.org does this work in other browsers?

Yes, this works very well on Windows with NVDA and both Chrome and Firefox, and also works well on Chrome OS with ChromeVox.
On those platforms you press Alt + / and begin to enter a search value and you immediately hear the number of results spoken, and can press up and down arrow keys to hear the results and press enter to make a selection.
This does not seem to work on Chrome on Mac. I did create a new profile on Canary with no apps or extensions and it still does not work using VoiceOver.

Thank you for providing more feedback. Adding the requester to the cc list.

Thanks for the reply, mjanusauskas@afb.org

I should have been more clear: does this work on other Mac browsers? 

For context, I'm trying to figure out if the issue is with Chrome or with VoiceOver (or with Docs, for that matter.)

Interestingly it does seem to work with Safari Technology Preview, but not with shipping Safari.

nektar@ do you know who would be the person to check into this? My totally uninformed knee-jerk opinion based on the above is making me think there's a new ARIA property involved or something similar.
