Bug 1572840 makes the RDM pane change size in response to full zoom. At low full zoom levels (30%), reported values of screen.width and window.outerWidth drift due to rounding error. See the test devtools/client/responsive/test/browser/browser_window_sizing.js.

Expected result is that documents in RDM panes should report screen.width and window.outerWidth exactly equal to the simulated device size at all zoom levels.
