Why does the confidence interval in Mood's median test seem one-sided?

Approximate visual representations of the confidence intervals are drawn with characters in the Session window. The minimum and maximum ends of the confidence interval are represented by opening and closing parentheses. The median is represented by an asterisk. Any (relative) space between the minimum and maximum and the median is represented by dashes. If, for example, the median was centered on the confidence interval, the output might be:


If, however, the median is relatively close to the end of the confidence interval, a dash will not appear between the * and the parentheses. For example:


Finally, if the median is very close to the end of the confidence interval, the confidence interval will stop with the *. For example:


In this case, the output for the test can seem to be one-sided.
