[Bug]: "Monitoring" notification hides "Compact" notification

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/web

Steps to reproduce

1. Start chat with fable 5
2. make it start a "monitor" and make the chat reach many tokens (>100k)

Expected behavior

You should simultaneously see two notifications:

• "Monitoring <stop>"

and a compaction notification:

• "Resume with less context <compact>"

Actual behavior

The monitoring notification covers the compaction notification.

What's strange is that when the mouse is specifically located in the thin blue region (the "compact" box above the "monitoring" notification) then the notification shifts to make both visible. This indicates that a fix was attempted but the visual fix only applies when the mouse is in the magic region not when it's anywhere else.

Impact

Minor bug or occasional failure

Workaround

Either don't compact, stop monitoring, or hover over the magic region to see both buttons properly.

Start in apps/web and reproduce the issue using the listed steps: run a fable 5 chat, start monitoring, and reach more than 100k tokens. Inspect the notification layout and hover-dependent behavior. Done means the “Monitoring” and “Resume with less context” notifications remain simultaneously visible without requiring the pointer to enter the thin blue region.
