(Accessibility) (ML) "WCAG 3.2.2 On Input does not cause a change of context"

[barlowm]

Steps to reproduce
Open Kibana and navigate to the "Machine Learning" section then tab through the buttons, the Screen Reader should announce the label associated with each button. Tabbing to the "Level" component, the Screen Reader reads "Button Level".
Activating the "Level" component opens a new dialog and adjusts the focus so the next tab will result in the focus being set on the first entry in the dialog. But the user is not informed prior to activating the "Level" component that a change in focus will occur.

An example of a better label for the "Level" component is the button for the "Calendar" icon above, which, when tabbed into, the Screen Reader reads "Date Quick Select Button", which informs the user that activating the button will present them with a way to select a date.
Suggest adding "Select" to the "Level" component so the Screen Reader will read "Level Select Button"

Screen Shot:

Expected Result
Activating the "Level" component, the screen reader should read "Level Select Button"

It also seems more like an EUI issue rather than an ML issue.
I've created an issue in EUI for that:
