Calling window.foo = 5 does not do make the variable global in Webview script

#48453

When I try to assign a global variable, such as doing window.foo = 5 in the Webview script, it is not available in the console of Webview developer tools.

OK, actually found I can access it in here:

I think this should go together with point 5 in #48705. Being able to interact with their script can help people with development/debugging a lot.

Good suggestion, I'll add a note on this. We cannot change the inspector behavior as far as I know

For verification, make sure the docs section on this makes sense and that you can follow the instructions to see state set in a webview

Fixed a quick typo in the section but makes sense
