Parent element might not be there after render

With a loading view, for instance.
So the extension crashes on parent.removeEventListener('click', handleClick); in runOnTransitionEnd, because the obj.element.parentElement is null.

CSS breaks my app

The first selector of in-page-styles.css breaks my app.

.ember-view:hover {
overflow: visible;

It is a scroll panel with a spy and that resets the scroll.

Times Hidden not persistent on reload

Would be nice if it would not always insert times into the view on reload.

Doesn't work with Ember loaded asynchronously

In our app we load Ember and other JavaScript assets on DOMContentLoaded event so they don't block rendering.

If I understand the code correctly this extension checks for Ember existance only once:
inPageScript.onload = afterInjection;

Ember Inspector doesn't have this problem so it should be possible to fix. Thanks in advance :)

Syntax error

Getting a weird error when the extension is enabled and I reload the app.

In content-script.js:

case 'HAS_EMBER':
if (request.hasEmber !== undefined) {
hasEmber = request.hasEmber;
sendResponse({ hasEmber });

On the sendResponse line, I get "Uncaught SyntaxError: Unexpected token }"
