E.g. The following example has no token list:
\A backslash is not considered a token by itself. It always requires something after (just as TeX does) The following example has a token list:
t\The t is a letter token, so a token list exists.
Describe the bug When I enter "\" at an Editor that inits with blank content, the browser would pop up this error. However, If enter some other keys first, then enter "\", everything is going completely correct.
