#556 added overflow-y-auto to the dialog content container. Per the CSS
spec, when one overflow axis is non-visible the other resets from
visible to auto, so overflow-x was being silently clamped too — clipping
the ~2px focus ring on inputs/buttons against the left edge of the
container.
Add px-1/-mx-1 so the layout width is unchanged while focus rings get
room to render.
