Why don TEX commands get expanded in the HTML title?

In HTML, the stuff that goes in the … of a page is not permitted by the specification to contain HTML tags – things in angle brackets – and tags are not interpreted. If an equation or some other command that TTH translates into HTML formatting is in the title, then the title will break when expanded. Therefore TTH never expands commands in the title, but leaves them in the TEX form that they started as, since that is about as easy to read as any unformatted mathematics.
