Web UI (mobile): session "Delete…" menu item unresponsive until long-press

Description

On the mobile Web UI, the "Delete…" item in the session overflow menu ("…" inside an open session) does not respond to a normal tap. Tapping it does nothing — no confirmation dialog appears. The item only works after a long-press on the "Delete…" row; then the Delete session "name"? confirmation dialog finally shows up.

This is very confusing for users — there is no visual feedback, so it looks like the button is simply broken/disabled. Users don't know how to use it.

Related: #37693 (same area, but that one reports flickering; here there is no flickering — the menu item just silently swallows taps).

Steps to reproduce

1. Open the OpenCode Web UI from a mobile device (Android).
2. Open any session.
3. Tap the "…" (more options) menu in the session header.
4. Tap "Delete…".
5. Observed: nothing happens — no confirmation dialog (Delete session "name"?) appears.
6. Long-press the "Delete…" row instead: the confirmation dialog now appears.
