Angular Material v 1.0.0 currently does not support an option not to scroll to top when using md-virtual-repeat when items are removed. This directive is a quick fix that overrides default behaviour. Usage:

<md-virtual-repeat-container>
    <div md-virtual-repeat="item in items" prevent-scroll>
    </div>
</md-virtual-repeat-container>

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

	require 'countries'
	require 'json'
	require 'active_support'
	require 'sort_alphabetical'

	lang = ARGV[0] \|\| 'cs'

	data = ISO3166::Country
	.all
	.collect {\|c\| {name: c.translations[lang], code: c.alpha2} }
