Description

This PR enhances iframe resizing behavior to dynamically adjust height and width based on content size and user interaction. Specifically, the height is recalculated with additional space (100px) when the braille-input field is focused, and 50px otherwise. This ensures the iframe is not clipped during braille mode. The script also adds event listeners for focusin, focusout, and resize events to trigger appropriate resizing as needed, which were added by @krishnanand5.

Hey @dakshpokar,

The changes are fine on Shiny. Thank you for taking care of the dynamic height adjustment when braille is active. Let me know if we can address my comments.

Regards,
Krishna Anandan Ganesan.
