<h3 dir="auto">Steps to reproduce</h3>
<p dir="auto">open console panel to check log</p>
<h3 dir="auto">What is expected?</h3>
<p dir="auto">loading initial data for options should not trigger a DOM "change" event (as it should be done by user)</p>
<h3 dir="auto">What is actually happening?</h3>
<p dir="auto">async data update will result with a DOM "change" event, while sync data update will not.</p>
<hr>
<p dir="auto">this should has something to do with <a href="https://github.com/vuejs/vue/commit/c70addf7d1a8e820ed80b6ab14aace5aa7b604c5">commit c70addf</a> and it was working fine with v2.4.1.</p>
<p dir="auto">my app should fire a form submit after user changed option, but now the app will submit right after data initialized. (check commented line in sample js)</p>
