💥 Actual behavior

After adding an Apple Business Manager token at Settings → Integrations → MDM → Apple Business Manager, opening the Edit fleets modal and clicking either the macOS fleet or iOS fleet dropdown for the first time shows the "Workstations" option highlight extending past the dropdown's left and right borders. The highlight bar visibly bleeds outside the dropdown container.

After a fleet has been assigned (i.e., once a selection is made and the dropdown is reopened), the highlight clips correctly to the dropdown's width on subsequent opens.

🧑‍💻 Steps to reproduce

These steps:

• Have been confirmed to consistently lead to reproduction in multiple Fleet instances.
• Describe the workflow that led to the error, but have not yet been reproduced in multiple Fleet instances.

1. Switch Fleet UI to dark mode.
2. Navigate to Settings → Integrations → MDM → Apple Business Manager.
3. Add an Apple Business Manager token.
4. Open the Edit fleets modal for the newly-added ABM token.
5. Click the macOS fleet "Select one..." dropdown.
6. Observe the "Workstations" option — its highlight extends beyond the dropdown's left and right borders.
7. Click the iOS fleet "Select one..." dropdown.
8. Observe the same behavior.
9. Assign a fleet, save, and reopen the modal — confirm the highlight now clips correctly inside the dropdown borders.
