Full Screen for Sketchpad and ImageEditor

• I have searched to see if a similar issue already exists.

Gradio version: 5.49.1

Is your feature request related to a problem? Please describe.
Sometimes the image editing interface becomes very small due to the component layout, which is very inconvenient to use. I set show_fullscreen_button=True, but it doesn't work, and I can't find where the fullscreen button is.

Describe the solution you'd like
I hope to have a fullscreen button similar to the Image component so that I can edit images in fullscreen.
