The CSS rule .o_action_manager { overflow: auto !important; } leaks
globally — Odoos outer action container is the same element across
EVERY page in the webclient. On viewports above the xxl breakpoint
(~1500px) this overflow setting collapses flex sizing of children,
shrinking form sheets to ~3mm. erp incident 2026-05-09: New Project
form on Construction app rendered as a 3mm-wide column. Visible only

breakpoints.
Move the overflow declaration INSIDE the .construction_dashboard
scope so it applies only on the dashboard page (where it was meant to
apply in the first place).
