Hm. Weird. It works using before-string and after-string, though.
Looking at preview-latex, it actually moves stuff from 'display to
'before-string in the zero-length case.
This can probably can well be considered a bug, but it is a bug that
has been around for eternities, so we are not going to win much
applause trying to fix it before the release.
Afterwards, however, should be a good time to tackle this
inconsistency along with the others.
