Mouse capture blocks right-click paste in Windows Terminal

Description

When using the OpenCode TUI inside Windows Terminal (v1.24) on Windows, the mouse option is an all-or-nothing switch:

• mouse: true (default): wheel-scrolling of chat history works, but right-click is consumed by the app, so right-click paste does not work even though Windows Terminal is configured with interaction.rightClick: "paste". Pasting only works via Alt+right-click or Ctrl+Shift+V.
• mouse: false: right-click paste works (Windows Terminal handles it), but wheel scrolling no longer scrolls the chat view (mouse events are not delivered to the TUI).

Expected behavior

Wheel scrolling and terminal-level right-click paste should be able to coexist. Ideally:

1. The mouse setting should be split, e.g. control wheel-scrolling / left-click separately from right-button capture, so right-click can fall through to the terminal emulator.
2. Or the TUI should not capture the right mouse button at all, leaving it to the terminal for paste / context menu.

Environment

• OpenCode TUI in Windows Terminal 1.24.11911.0
• OS: Windows
• Config: ~/.config/opencode/tui.json (also tui.json global config)

Workaround today

mouse: true + Alt+right-click to paste, or switch mouse: false and give up wheel scrolling in the chat view.
