1.0.2
Upgrade to package.json to include the latest version of ember-cli-text-support-mixins. The Enter & Ctrl+Enter submitting form has been known to double-submit if the form has a button of type="submit" contained within. Chrome & Safari will not suffer this double submit, however Firefox does continue to suffer double-submits.
Workaround
Do not include a button of type="submit" inside your form if you desire that the {{input-date}} and {{input-iso8601}} components to submit the form on Ctrl+Enter.
<form ...>
{{input-date ...}}
<button type="submit">Submit</button>
</form>
...should instead be changed to:
<form ...>
{{input-date ...}}
<button type="action" {{action "submitTheFormUsingAnAction"}}>Submit</button>
</form>
