tests are not passing

I'm trying to file several issues along with tests. It seems that currently there are several (4 tests) falling. Is this expected?

 1) Bootstrap test
       "before each" hook for "can morph content to content":
     TypeError: Cannot set properties of null (setting 'innerHTML')
      at clearWorkArea (test-utilities.js:43:29)
      at Context.<anonymous> (bootstrap.js:4:9)

  2) Tests to ensure that idiomorph merges properly
       "before each" hook for "morphs text correctly":
     TypeError: Cannot set properties of null (setting 'innerHTML')
      at clearWorkArea (test-utilities.js:43:29)
      at Context.<anonymous> (fidelity.js:4:9)

  3) Core morphing tests
       "before each" hook for "morphs outerHTML as content properly when argument is null":
     TypeError: Cannot set properties of null (setting 'innerHTML')
      at clearWorkArea (test-utilities.js:43:29)
      at Context.<anonymous> (core.js:4:9)

  4) Tests to compare perf with morphdom
       "before each" hook for "HTML5 Elements Sample Page":
     TypeError: Cannot set properties of null (setting 'innerHTML')
      at clearWorkArea (test-utilities.js:43:29)
      at Context.<anonymous> (perf.js:4:9)
