Summary

Ensures the WebAgg server URL is always displayed to users, even when the browser successfully opens automatically.

Problem

Currently, the URL is only shown when:

• webagg.open_in_browser isFalse, OR
• The browser fails to open

This means users never see the URL when the browser opens successfully, making it difficult to:

• Share the URL with others
• Open in a different browser
• Reconnect if the tab is accidentally closed

Solution

Moved theprint(f"To view figure, visit {url}") statement outside the conditional block, ensuring it always executes regardless of the browser open attempt.

Changes

• File:lib/matplotlib/backends/backend_webagg.py
• Method:FigureManagerWebAgg.pyplot_show()
• Simplified conditional logic
• URL now prints in all cases

Benefits

• ✅ Users always know the exact URL to access their figures
• ✅ Easier to reconnect if browser tab closes
• ✅ Better user experience for remote/headless environments
• ✅ Consistent behavior regardless of settings

Testing

Tested with:

• webagg.open_in_browser = True → URL displays, browser opens
• webagg.open_in_browser = False → URL displays, browser doesn't open
• Simulated browser open failure → URL still displays
