format does not remove all the comments with strip_comments=True

[rkrenzler]

Describe the bug
sqlparse.format(query, strip_comments=True) sometimes does not strip all the comments from the query in sqlparse versions 0.5.2 and 0.5.3.

To Reproduce

import sqlparse

query = "--A;\n--B;"
result = sqlparse.format(query, strip_comments=True)

result is --B;

Expected behavior
result should be empty. It is empty in sqlparse version 0.5.1 but not in 0.5.2 and 0.5.3.

Versions:

• Python: 3.11.9
• sqlparse: 0.5.2 and 0.5.3
