Clicking browser back button from an error page to a non-error page, retains the styles of the error page

[rsukale]

Here's the scenario

/page-valid (valid route in the app)
/page-invalid (this route does not exist)

if /page-valid has a link to /page-invalid, and the user clicks on it, we get the standard rails error page as expected, with all the red colors.

Now if the user presses the back button to go back to /page-valid, the styles from the error page are retained.
