[SelectField] Browser address autofill does not work when used for the state field

[gmacciocca]

Description

I have an address form where for the "state" two letter code, I use material-ui SelectField. Problem is that this SelectField does not autofill with the correct state code, when the browser proposes an autofill address. All other text fields (address, city, zip-code) autofill correctly. I've tested this with Chrome/Firefox/IE/Edge/Safari.
I posted this question on stackoverflow a few days ago, but received no answer.

Problem description

The SelectField for the state does not fill in response to the autofill data provided by the browser.

This is because SelectField is composed of <div>s etc. rather than using a native select> form element.

A hidden shadow element could in theory be used to capture the input, buts some browsers don't trigger DOM events on autofill as a security precaution, so it wouldn't be possible to determine that a value had been provided without continuous polling.

This is the same issue we have with the text field label not animating on autofill.

Thanks, @mbrookes. So do you think I'm better off stop using SelectField? Submitting a fix would probably take me some time, but I can try. How likely is that this will be looked at by some of the main contributors?
Thanks.

I can't see it being a high priority right now, as the focus is on porting to the new styling approach on the next branch, and there is no easy fix AFAIK.

Still noticing this issue on newer versions, I don't see specifically how #8023 resolves this issue.
