[2.1.0] Sometimes WYSIWYG editor does not show.

[peec]

Preconditions

1. PHP 7.0.3
2. Mysql 5.6
3. Latest chrome browser
4. Magento environment: Production
5. JS / CSS minifcation and merging enabled.

Steps to reproduce

1. Go into any page with a wysiwyg editor possiblity ( e.g. product edit page ).
2. See that sometimes it does not appear
3. Try clicking "Show editor". Nothing happens.
4. If you click the "Show/Hide editor" and do F5 refresh the page, suddenly the WYSIWYG editor shows.

Expected result

1. When toggling between Show/Hide editor you should get the WYSIWYG editor.

Actual result

Editor not showing (randomly) . Sometimes it does, sometimes not. A browser refresh might do so the editor opens..

This is not completely random.

Steps to reproduce

Method 1:

1. Go to Content > Pages in backend
2. Edit any page but while editing right click on the Edit link and open the link in a new page.
3. Wait for the page to be loaded before switching to the page.
4. The WYSIWYG editor will not be loaded

Method 2:

1. Reload the page, but switch to another tab quickly.
2. Wait for the page to be loaded.
3. The WYSIWYG editor will not be loaded.

Method 3:

1. Reload the page
2. Stay on the page until it is completely loaded.
3. The WYSIWYG editor will now be loaded.
4. For that tab, the WYSIWYG editor will be loaded even if we reload the page and switch to another tab.
5. Close that tab, and go through Method 1 for that same page, the WYSIWYG editor will not be loaded

I tested this using a fresh M2.1 installation without any customization or sample data.

I have been having the same problem with the WYSIWYG as well on M2.0.7 and M2.1.

Thanks @vivek201 for figuring out how to reproduce the problem.

@MomotenkoNatalia Thanks for the response! I was starting to wonder if this was an issue on just my system.

I am seeing the same issue with 2.1.1. The WYSIWYG editor shows up after refreshing the page and staying on it until it fully loads again.

[SerhiyShkolyarenko]

Fix is delivered to the develop branch. Closing the issue.
Issues for backporting to 2.0.x and 2.1.x branches are MAGETWO-59691 and MAGETWO-59688 correspondingly.
