Bug 1407366 - Part 5: Reset the Zoom in browser_bug1369357_site_specific_zoom_level.js r=johann

This test changes the browser zoom level; but does not reset it; causing subsequant tests to be run with a zoom. This may cause them to fail. --- .../test/browser/browser_bug1369357_site_specific_zoom_level.js | 2 ++ .../test/browser/browser_dynamical_window_rounding.js | 4 ++++ 2 files changed, 6 insertions(+)
