Revert "sidebar: Zoom temporarily hides sidebar (#50088)" (#50297)

Anthony Eid created 1 month ago

This reverts commit aa3a12b566, because we no longer want a zoomed item
to block the sidebar.

This is because the sidebar is used for navigation and it interrupts a
user's flow if they're scrolling through their active workspaces, and
the sidebar just vanishes.
