fix not able to exit metadata popup when pop up is too big

[w-e-w]

Description

sometime the extra network cards metadata pop up can be too big as to take up the entire screen
when this happened it is not possible to exit the metadata pop up

solution
add max-height: 90%; and max-width: 90%; .global-popup-inner
this prevents the pop-up from being too big as to making exiting the pop-up impossible

this is what I came up with using my limited web development knowledge

How about using Escape?

window.addEventListener("keydown", function(event) {
    if (event.key == "Escape") {
        closePopup();
    }
});

How about using Escape?

does escape work for mobile?

Not without a keyboard. I mean in addition to your solution. The image viewer closes with escape, so might as well do it for the other popups.

stable-diffusion-webui/javascript/imageviewer.js

Lines 116 to 117 in 4afaaf8

	case "Escape":
	closeModal();

ahh, no objection, all for it in fact it make sense.

I think you can push to this PR, unless you wanted me to do it?
