[TYPO3-core] RFC #16049: Loading mask doesn't disappear on hitting Esc/cancel loading

[Steffen Kamper]

Hi Steffen,

first +1 by reading and testing though i see no possibility to do 
anything after hitting escape. Even if you have unsaved data, the 
browser is stopped.

After some research there seems no way to do something, i only found one 
obscure solution with server driven event "server-time" (which is opera 
only?)

Anyway it's useful to remove the masj on click.
For CGL please use this styling:
this.el.child('.x-mask-loading-message').on(
	'click',
	function() {
		this.el.unmask();
	},
	this
);
