The Timezone field (and the voice/model ComboboxInput) pinned the popover to
--radix-popover-trigger-width. In the settings grid the trigger shrink-wraps to
its current value (~90-120px), so every IANA row was clipped to "Africa/A…" and
the picker was unusable by eye even though selection itself worked. Use min-w so
the list keeps its own width and only grows to cover a wider trigger.
Live-verified on a sandboxed Electron instance over CDP: popover 123px -> 288px,
rows no longer overflow; click, type+Enter and autosave to config.yaml all land.
