Hello,

I am creating component using following markup as template:

<div :class="{'inner-class': true}">Stuff<div>

Then I am using this component as follows:

<my-component class="outer-class"></my-component>

I would expect to see <div class="inner-class outer-class"> as a result and it's true for modern browsers. Unfortunately on IE9 (real one, not emulated mind you) class is empty.

Is t a bug or am I missing something?
