Uuh... I did not recognize that I am the assignee of this issue. I will have a look at the coding night in Malmö.

You're not the assignee but it looked like this ticket was somehow "forgotten".
But cool if you can have a look on your own!

Steps to reproduce it on 8.7.13:
1) create custom worskpace
2) create a page and some content
3) modify the content in the workspace
4) click on the view button to preview the page with the "workspace bar"
5) use chrome console to see errors
results: see attached screenshot

The issue behind this is CORS and the usage of setting "document.domain" ... see https://developer.mozilla.org/en-US/docs/Web/API/Document/domain
The ContextHelp.js searches for the real backendWindow (from which the Workspace preview was opened as "popup").
The Workspace Preview and Review system uses "document.domain" to set a Domain (since minimum TYPO3 4.5) for CORS in the iframes but as the real backendWindow do not set such thing we are decoupled (in the CORS view).
1) Remove all document.domain things from workspace
- This worked as expected, as the real backendWindow, the "popup" and the iframes inside the "popup" are loaded from same domain. The mentioned parent.resize functionality seams an old comment, slider/tabs & co worked correctly.
- I tested on Linux with
- Chrome 65.0.3325.181
- SeaMonkey 2.49.2
- Firefox 59.0.2
- On Windows
- InternetExplorer 11.0.9600.18977
- Firefox 59.0.3
- Someone should test this with IE
- This needs then also added to all PopUp/Wizards which try to communicate with this backendWindow
- This would be a breaking change ... also inside backporting to 8 LTS
- Could produce more hassle then it resolves
- IMHO this is not a real solution as we may later come up to a point where we need to communicate with backendWindow
Summa Summarum, I would favor solution 1.

ckeditor seams to use an extra function for IE to circumvent an CORS issue there:
