Enabling “Notifications” prevents post text from being edited in Mobile Safari

[hugocf]

Summary:


Cannot edit text in the TinyMCE “Visual” editor via an iOS browser when the Edit Flow “Notification” are enabled.

**Steps to Reproduce:
**

1. In the admin pages, enable “Edit Flow” > “Notifications”
2. Navigate to the admin pages and login via Mobile Safari
3. Edit an existing post
4. With the TinyMCE editor in “Visual” mode, touch the text to edit it

Expected Results:

The keyboard should show up and a text editor cursor should appear at the touch point.

Actual Results: 
 Nothing happens. No matter how many touches, it doesn't enter the edit mode.

Regression:

Switching to “HTML” editing mode causes the text editing to be possible again. Switching back to “Visual” mode reverts back to the problem.

This happens both using an iPhone and an iPad, running the latest iOS 7.1 version, and occurs using both Mobile Safari and Google Chrome.

Notes:

Once we enabled the Edit Flow “Notifications” feature, which adds a box to select the people to notify at the end of the post edit screen, we stopped being able to edit the post text in iOS.

If we disable the Edit Flow “Notifications” feature, we regain the ability to edit the posts via Mobile Safari.

Editing the “Title” or the “Excerpt” fields, which are not TinyMCE fields, always works fine.
