Issue Summary

When hovering over the left-side page menu, Atlasian Intelligence auto-enables the page summary. If the page contains text with underscores (_) at the top, enclosed between shebang markers (e.g. – =========================== before and after the text), the AI snippet banner fails to load, causing the browser to hang indefinitely until the tab is closed.

Steps to Reproduce

1. Create a page with text at the top containing underscores, enclosed between shebangs such as:

   • -- ================================
     -- some_text_with_underscores
     -- ================================

1. Hover the mouse over the left-side page menu.

Expected Results

• AI Snippet page summary should display.

Actual Results

1. AI snippet page summary will show "Atlassian Intelligence is working..." 
   • 
2. AI snippet banner hangs and never loads.
3. Page becomes unresponsive, requiring the browser tab to be closed and reopened.
   • 

Workaround

1. Remove or replace underscores (_) with hyphens .
2. If underscores must remain, change the shebang from:

   • -- ================================
     -- some_text_with_underscores
     -- ================================

• • To:

  • -- ------------------------------
    -- some_text_with_underscores
    -- ------------------------------
