@arapte - can you review this?

The only question I have is whether is is expected that `dragTabHeader` can be null. If we understand why it is null, and that it isn't an error for it to be null, then the fix is fine. If its being null is unexpected, then the fix might just be masking the real problem. There isn't enough information in this PR to be able to evaluate this.
