Codex found the body-reparented picker (z-200, later body child) could be revealed
UNDER a full-screen drawer/panel via multiple paths (swipe, breakpoint resize,
profile-switch). Rather than guard each open-site (whack-a-mole + my resize guard
over-fired on keyboard reflows), fix the class once: .model-dropdown--floating gets
z-index:190 — above the composer-mobile-config-panel (z-180) it opens from, below
the mobile sidebar + workspace panel (both z-200) — so any drawer/panel that opens
covers the picker, matching master's stacking intent. Reverted the two boot.js
guards. Co-authored-by webtecnica.
