:::::::: Well, you say "''Since whitespace is optional ...''", but where ? In what specific context is it optional ? HTML ? Latex ? The Wiki software's Latex-to-HTML preprocessor ? The technical contexts for that statement are rather ill-defined. The context that really matters, and of which we '''do''' have a clear picture, is that of the value for users. Experiment is showing us clearly and unambiguously that in that context the whitespace is '''not''' "optional" – introducing it creates no value for any users, but it does entirely remove formula visibility for significant numbers of users.

:Just to add to the puzzle, with Firefox a formula expression preceded or followed by a space (as exemplified above) evokes a garbled complaint in startling big red letters: (I've removed the text of the formula from the end)
<pre>Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("<p>There was a problem during the HTTP request: 502 Bad Gateway </p>") from server "http://mathoid.testme.wmflabs.org":):</pre>
:Without such spaces, Firefox renders the formula, but other browsers don't. Other web pages seem to employ an image file, or a collection of images of symbols to obtain a pleasing result. If I understand matters correctly, the RC system sends (or could send) different .html stuff according to the name of the browser it is feeding, so, I'm well adrift.
