johnjamesjacoby f60dae0731 Admin/Menu: include 960 exact pixel width in collapse measurements.
This change removes a 1 pixel gap in the measurement of the viewport width when clicking the "Collapse menu" button (at the bottom of the admin menu UI) when already collapsed, causing the menu not to open as intended when exactly 960 pixels wide.

Before this change, the menu would be stuck in the collapsed position. After this change, the menu opens as expected.

Fixes #54210.
