it addresses the iframe modal dialog scrolling issue by:
1.CSS Improvements: Added proper overflow handling for iframe content
Dynamic Class Management: JavaScript automatically applies has-modal class when modals open
2.Scrolling Support: Ensures modal dialogs can scroll when content exceeds viewport
3.Backward Compatibility: Maintains existing functionality while fixing the display issues

I'm not familiar with the code, but looks like a valid solution.

Reproducible: Always
