Bug: double click on a widget inside TinyMCE editor does not edit the widget but creates a new one

To reproduce the bug you need to fix the #2235 bug first.

Hi @shiftedreality just wondering if you have an update on this? We're seeing this issue on our 2.1.4 installation. I've checked the commits referenced in #2235 and have confirmed they are currently in our codebase but we are still seeing the issue.

Hello,

Same issue in Magento 2.1.7.

Steps to repeat

1. Go to Admin -> Content -> Pages, and edit a page.
2. Add a new widget to the page
3. Select Catalog Product Lists as the widget type.
4. Added Required Field
5. Click on "Insert Widget"
6. Click on "Click on "Save and Continue Edit"
7. Double Click on "Widget icon"

Expected result:
Widget open with selected/filled data

Actual result:
Widget open as new

Js Error:
Uncaught DOMException: Failed to execute 'setBaseAndExtent' on 'Selection': There is no child at offset 1. In tiny_mce_src.js
Line No.: 1173

@nilarocks: the error you are reporting is a different problem, it's this one: #9518 which has been fixed in Magento 2.1.8.
