[Feature Request] Touchscreen support

Nobody has claimed this yet.

With the upgrade to Gradio v4, touchscreen-only workflows have become quite challenging because the context menu of the canvas control appears 'on hover', causing it to appear and disappear when one interacts with the interface.

Is there a way to change this hover behavior in the configuration, or at least make an option available to revert to a behavior more like the previous version? I use Forge on my iPad and can upload images using a quick double-tap just slightly right from the top-left corner of the canvas. However, this method is tricky and if missed, it opens the full-screen canvas which is difficult to close.

For me, being able to use Forge on an iPad is a significant advantage over other node-based UIs (like ComfyUI) that are impossible or difficult to use from anything but a computer.

Start by reproducing the canvas context-menu behavior on an iPad with the Gradio v4 interface, focusing on hover-triggered appearance and accidental full-screen opening. No source file or test is identified in the issue; done should mean touchscreen-only users can access the canvas actions reliably without the menu disappearing or becoming difficult to close.
