Problem with new link popup in WYSIWYG Editor

[manuelmoreale]

Issue description:

There's a problem with the new modal introduced in WP 4.5.
Actually there are 2 bugs.

One is related to the z-index and is an easy fix. The modal has a z-index value of 100100 while the main div containing the content of the customizer has a z-index value of 500000

The second bug is a bit more tricky. The popup is displayed using absolute positioning relative to the selected word in the editor and has 4 different alignments. Top and bottom are not a problem since there's always some space on top or on the bottom of the editor. Left aligned is also not a problem since on the right there's the entire screen to work with. The problem is the right aligned. Here's a screen that shows the issue:

As you can see the modal goes out the screen on the left side. The modal is quite wide (almost 400px) so using a wider sidebar is not a solution.
Haven't had time to look into the new link modal to see if there's a way to fix this one.

I hate the WYSIWYG editor...

Can you please try the develop branch now?
editor fields were completely refactored trying to resolve #140 and I think this one was also resolved with it 👍

Closing this one. :)
According to the comment on #914 (comment) it has been resolved.
