> In the following code, the `precedingsTokens` list should contain two elements. In fact,
it does, but the `size()` method of the list still returns 6. That is because `org.apache.uima.cas.impl.SelectFSs_impl.asList()`
simply uses the size of the underlying index and does not take into account limit or direction
options from the select.

>     *new* Token(jCas, 1, 2).addToIndexes();

>     *new* Token(jCas, 4, 5).addToIndexes();
>     *new* Token(jCas, 1, 3).addToIndexes();
>     Token c = JCasUtil.selectAt(jCas, Token.*class*, 2, 3).get(0);
>     List<Token> preceedingTokens = jCas.select(Token.*class*).preceding(c).limit(2).asList();
>     
>     assertEquals(2, preceedingTokens.size());
