alert and prompt notification scroll to bottom

[danielghost]

If the notify content overflows, as focus gets applied to the buttons for alert and prompt types, the content opens already scrolled due to the position of the buttons.

This can be resolved by forcing the scroll back to the top in onLoaded:

adapt-contrib-core/js/views/notifyPopupView.js

Lines 133 to 148 in 75e0ab9

	async onLoaded() {
	this.hasOpened = true;
	// Allows popup manager to control focus
	a11y.popupOpened(this.$('.notify__popup'));
	a11y.scrollDisable('body');
	$('html').addClass('notify');
	this.$el.addClass('anim-show-before');
	// Set focus to first accessible element
	a11y.focusFirst(this.$('.notify__popup'), { defer: false });
	await transitionNextFrame();
	this.resetNotifySize();
	await transitionNextFrame();
	this.$el.addClass('anim-show-after');
	await transitionsEnded(this.$('.notify__popup, .notify__shadow'));
	}

const $dialog = this.$('.notify__popup');
$dialog.scrollTop(0);

a11y.focusFirst(this.$('.notify__popup'), { defer: false, preventScroll: true });

I think the buttons have already received focus before the focus is redirected via a11y.focusFirst(this.$('.notify__popup')..., so preventing the scroll doesn't fix the problem. May need further investigation to understand why the button is alreday focused.
