Mac app: conversation text hidden behind input bar after crash recovery

Description

After a session crash and the full-window "back to ***" recovery modal, the conversation view doesn't scroll far enough to show the last ~3 lines of the assistant's most recent response. The input bar and branch/PR toolbar overlap the bottom of the conversation.

Steps to reproduce

1. Have a conversation in the Claude Code Mac app
2. Experience a session crash (in my case, triggered by large AppleScript/Mail output)
3. Click through the crash recovery modal
4. Try to scroll to the bottom of the conversation

Expected behavior

Full conversation text visible above the input area.

Actual behavior

The last ~3 lines of the assistant's response are hidden behind the input bar + branch toolbar. Cannot scroll further down.

Impact

This causes the user to misread the conversation flow — responses appear to answer the wrong questions because the user can't see the bottom of each message. Particularly bad in back-and-forth workflows.

Environment

• Claude Code Mac app (desktop)
• macOS Sequoia
• Opus 4.6
