Clicking an async-button in QUnit test does not work but works fine with HTML button

[jackmatt2]

I have the following test which is trying to click a button is inside a modal.

  const selector = `button:contains("${buttonText}"), a:contains("${buttonText}")`;
  const found = find(selector, Ember.$('body'));
  assert.equal(1, found.length, `Should find the button or link with text "${buttonText}"`);
  click(selector, Ember.$('body'));  <--------- button click
  found.click();  <--------------- does not work either

In the modal I have tried the following button types.

  // (FAIL) If the button is an async button it does not fire the action at all
  {{async-button class="btn btn-primary" type="button" action=(route-action 'save' model) default="Proceed" pending="Saving..."}}

  // (SUCCESS) The same test but using a regular button and the action is fired
  <button class="btn btn-primary" type="button" onclick={{route-action 'save' model}}>Proceed</button>

The button click fires without any errors in both cases so it is not like the button is not found.

The reason for passing a context to click and find is that without it QUnit was unable to find the control as it is rendered inside the application template.

This is probably a problem with ember-tether, can you confirm? @jackmatt2
