Added negative reference-orientations to block-container4.

Now checking the CTMs, too
New block-container4a based on the test case submitted by Yannick Valot for Bugzilla #36391.
I had to disable block-container4a because the CTM for 180/-180 is really wrong. Comment about the defect added to the checks. There's no quick fix, but this is also low-priority for me.
