How to get navigator.webdriver?

[Elufimov]

Summary

Webdriver getter exists in NavigatorAutomationInformation https://rustwasm.github.io/wasm-bindgen/api/web_sys/struct.NavigatorAutomationInformation.html#method.webdriver and obviously this code

 let window = window().expect("no global `window` exists");
 let navigator = window.navigator();
 let webdriver = navigator.webdriver();

will result to error

error[E0599]: no method named `webdriver` found for type `web_sys::Navigator` in the current scope
  --> src\lib.rs:27:32
   |
27 |     let webdriver = navigator.webdriver();
   |                                ^^^^^^^^^

And I cant cast Navigator to NavigatorAutomationInformation.

@Elufimov navigator.webdriver is an experimental API which has not been standardized yet. We only support standardized APIs.

We've discussed adding in support for unstable APIs, with the caveat that they can break at any time, so you can't rely upon them.

On the other hand, perhaps we can make an exception here, since it seems to be supported in all browsers, and it's just a simple bool, nothing complex.

Supporting only stable set of api is completely reasonable.

If this is possible it would be great.

Seems reasonable to me to add if everything already supports it!

I'm going to close this in favor of #1950 which tracks how we'll be handling unstable web features (or at least not yet standardized)
