This is really a duplicate of bug 423544 which is about a supported component and was closed by mistake.

Seems it works for regular thumbnails, but the preview panel ignores it. Is this what you are experiencing too?

This report is about the regular thumbnails, and currently I'm unable to reproduce the reported issue.
But I can confirm that the preview panel ignores the setting.

Alright, if you can't get the issue anymore I think we can close this. The preview panel showing thumbnails even with this setting works as intended. Thanks for the report!
