What steps will reproduce the problem?
(1) Create a html page with a <form> and several <input type="text"> elements in the form.
(2) Add the autocomplete="off" attribure to some of them, for example the first one or two.
(3) Fill all autocomplete="off" inputs with data. Optionally fill other inputs with data.
(4) Redirect the user to another page, for example with window.location = 'other.html'.
(5) Hit backspace or the back button on the browser or device.
(6) The first page's inputs have remembered the data inserted in them before navigation to the other page.

What is the expected result?
The inputs contain the data inserted previously. Alternatively, the page is reloaded and the data is lost.

What happens instead?
The data that was inserted into autocomplete="off" inputs has copied itself into inputs where it was not inserted into.
