[Bug]: Selected Codex driver border briefly clips after switching wizard tabs

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/web (observed in the macOS desktop app)

Steps to reproduce

1. Open Settings → Providers → Add provider instance.
2. On the Driver tab, leave Codex selected.
3. Click Config without entering identity details. The wizard shows Identity with an “Instance ID is required” message. Click Driver to return to the driver selection.
4. Watch the left edge of the selected Codex card immediately after switching back. Repeat the tab switch if needed.

Expected behavior

The selected Codex card keeps its complete rounded purple selection border throughout the tab transition.

Actual behavior

The left edge of the selected Codex card's purple border is briefly clipped after returning to Driver, then restores itself. The card remains selected and its checkmark stays visible. The clipping is visible around 00:03.25 in the recording.

Impact

Cosmetic issue

Workaround

Wait briefly after switching back to Driver; the border restores itself without changing the selection.

Start in apps/web by tracing the provider-setup wizard's Driver and Config tab transition, then reproduce the Codex selection case described above. Inspect the selected card during the transition and verify that its complete rounded purple border remains visible before considering the issue done.
