Intercept popup (target=_blank) in CEF3 (Chromium)

I have made a simple tabbed browser with CEF3, which works well,
except that popups open in their own window.

When a link is clicked with "target=_blank", the OnBeforePopup event
fires. So far, so good. I create a new TTabSheet and a new TChromium.
Then I set the parent of that new Chromium to the TTabSheet, and I get
a SIGSEGV.

Code: [Select]  Result := TTabSheet.Create(MyPages);
  Result.Parent := MyPages;

  ...
 
  ch := TChromium.Create(Result);
  ch.Parent := Result;    <--- SIGSEGV

After googling and reading what I could find on the Chromium Embedded
Framework Forum, it seems that it might be that the popup has already
been created, and that I have to attach the ICefBrowser in it to
another TChromium. But everything I tried to make that happen resulted
in SIGSEGV's as well.

So, I was wondering if someone knows how I can assign the parent
without it crashing, or knows of a better solution?
