[macOS] Codex Micro action picker does not scroll with mouse or trackpad

What version of the Codex App are you using (From “About Codex” dialog)?

26.908.40834 (build 8881), read from the installed app bundle metadata.

What subscription do you have?

Not provided.

What platform is your computer?

macOS 26.0.1 (25A362)
Darwin 25.0.0 arm64 arm

These environment details are from the Mac used to submit this report; versions on all tested devices have not been separately confirmed.

What issue are you seeing?

In Codex Micro settings, the action picker in the “Edit keycap” dialog does not scroll with mouse or trackpad gestures. I have observed this with:

• Apple Magic Mouse
• Apple Magic Trackpad
• MacBook Air built-in trackpad

After focusing the list, repeatedly pressing the Down Arrow key moves through the actions and scrolls the list to reveal lower items. This provides a keyboard workaround, but the action list cannot be browsed normally using the mouse or trackpad.

The affected control is the popup opened by “Choose” under “Assigned action”, with a “Search actions” field at the top. My UI is in Japanese: “キーキャップを編集” → “割り当て済みのアクション” → “選択”, and the popup search field reads “アクションを検索”.

What steps can reproduce the bug?

1. Open Codex Micro settings and edit a keycap.
2. Click “Choose” under “Assigned action”.
3. Place the pointer over the action list and try to scroll using a mouse or trackpad.
4. Observe that the list does not scroll.
5. Focus the list and repeatedly press Down Arrow. The selection advances and the list scrolls to reveal lower actions.

What is the expected behavior?

The action list should scroll with mouse and trackpad gestures, allowing all actions to be reached without keyboard navigation.

Additional information

Related: #35244 concerns clipping in the same action picker on Windows. This report concerns mouse/trackpad scrolling on macOS; a shared cause has not been established.

The device behavior above is based on my manual observations. No root cause has been confirmed.

Start at Codex Micro settings, open the keycap editor, and inspect the action picker opened by “Choose” under “Assigned action.” Reproduce the issue with mouse or trackpad scrolling and verify that the action list can browse to lower items without keyboard navigation; compare the keyboard workaround while tracing the picker behavior.
