Obviously a very reputable source!

The entiy definitions that do use combining characters precede then with 
a space character so that the entity set as a whole meets the w3c 
charmod requirements that all replacement texts are NFC normalised, and 
don't start with a combining character. (Which is a sufficient, although 
not strictly necessary condition to ensure that unicode normalisation 
and entity expansion may be done in either order.)

A mathml renderer is supposed to ignore trailing and leading whitespace 
in mo so <mo>&#x20DB;</mo> and <mo> &#x20DB;</mo> should be treated 
equivalently, although <mo>&tdot;</mo> is equivalent to the latter.
