paper-dialog-inner does not get md-content-overflow class unless img element present

[rpkwv8]

The contentOverflow classBinding is only assigned in the callback of img element load event. If I do not have an img element in my paper-dialog, md-content-overflow class is never assigned and the border styling separating scrollable content from the dialog actions is shown. Link below is to the lines responsible. Angular material determines overflow twice-- once in $$rAF and then again after images are loaded. Ember-paper should do the same.

ember-paper/addon/components/paper-dialog-inner.js

Lines 35 to 45 in 69cc168

	imagesLoaded() {
	let content = this.element.querySelector('md-dialog-content');
	this.set('contentOverflow', content.scrollHeight > content.clientHeight);
	},
	didInsertElement() {
	this._super(...arguments);
	// content overflow might change depending on load of images inside dialog.
	let images = this.$().find('img');
	images.on(`load.${this.elementId}`, run.bind(this, this.imagesLoaded));
	},

This should be fixed on master. Thanks. 👍
