GitHub Issue: Text Selection in Dialog Captures Background Content in iTerm2

Title

Text selection in authorization dialog includes content outside dialog boundaries when using Cmd+Click or drag selection in iTerm2

Description

When using opencode in iTerm2, the OAuth authorization dialog has text selection issues that make it difficult to copy the authorization URL.

Environment

• Terminal: iTerm2
• Application: opencode (TUI)

Problem

The authorization dialog displays a URL that needs to be copied, but text selection behaves incorrectly:

1. Cmd+Click selection: Only selects text from the clicked line, missing the full URL
2. Drag selection: Selects text outside the dialog boundaries, capturing background terminal content

Expected Behavior

• Text selection should be constrained to the dialog content only
• Users should be able to easily select and copy the complete authorization URL

Example of incorrectly selected text:
