Example and result

When using \a and \b together the first word following is in bold and italic the second word is in the form as specified by the first used of \a and \b.
The documentation states that the next word after \a, \b will be in italic / bold, nothing is specified about using 2 of these together, so probably an unforeseen side effect. Problem can be overcome by using the HTML tags <em> and <b>.

Example code:
/**
  * Example for \\a \\b problem<br>
  *  using \\a: \a italic more words<br>
  *  using \\b: \b bold more words<br>
  *  using \\b \\a: \b \a bold_italic bold more words
  */
void(int a)
{
}
