I forgot complication #3:
3. If the file you are reviewing has an embedded transparent area, you
won't be able to check the BFC'ness of any surface viewed *through* the
transparent area. You can fall back on viewing the part with mytest6
turned off, or you can edit the part file, commenting out lines for the
transparent area. Fortunately, current part-authoring standards direct
authors to put part components in separate files; these separate files
can be individually reviewed for BFC compliance.
