When two CKEditor instances are first opened and then the browser is resized; JS errors.
Any time the browser is resized content is lost.

Introduced by LPS-46302. LPS-46302 destroys the editors and reloads them. There shouldn't be any issue with doing this. One editor at a time works fine. This might be an issue with CKEditor. A demo with CKEditor alone would need to be created to verify.

Steps to Replicate:

1. Place both Wiki & Message Boards on the same page.
2. Click Edit on the Wiki FrontPage
3. Click Post New Thread on the Message Boards
4. Add content to both the Wiki & the Thread CKEditors
5. Resize the browser significantly. Enough to trigger a phone/tablet breakpoint.

Expected Result:

• No JS errors.
• No loss of content.

Actual Result:

• JS error within CKEditor code. TypeError: Cannot read property 'destroy' of undefined
• Loss of entered content.

QA has a test that tests two CKEditors on the page. A similar test should be created to also resize the browser.
