Original change's description:
> Fix accessible name for input type=file
> 
> A file picker control (<input type=file>) is exposed as
> a button in the accessibility tree. Previously the
> filename chosen was only exposed in the accessible value,
> like with other input elements - but most screen readers
> were not reading the value, since it's not normal to
> read the value of a button. So users couldn't tell what
> file was chosen, or whether a file was chosen at all.
> 
> Fix this by making the accessible name include both the
> filename (as already exposed in the value) and the
> text of the "Choose File" button.
> 
> Add a test to confirm this is working correctly when a
> file is selected.
>
