Bug 1082139 - JavascriptException: JavascriptException: TypeError: window.getComputedStyle(...) is null at: app://callscreen.gaiamobile.org/gaia_build_defer_index.js line: 146

Why do we need the ```!view```? Also, the precedence here is unclear at a glance. We should write this instead as:
```js
var computedStyle = window.getComputedStyle(view);
if ((!view.value && !view.textContent) || !computedStyle) {
// ...
```
