We won't be passing custom phrases to these browser tooltips as the default text is descriptive enough for its purpose. Using a localised version of the browser should present these default messages in the correct language. If they don't, that would be a browser issue and worth reporting to the browser developers as a bug.
The inputs being hidden from view, however, is something we've added code to anticipate generically across the software so that we now ensure the input is scrolled to and visible if it isn't already visible.
