count(*) always returns 0 if table has a vector index

conn = libsql.connect(":memory:")
dims = 4
conn.execute(f"""

conn.execute("CREATE INDEX vector_idx ON vectors(libsql_vector_idx(vector))")
data = []
for primary in range(10):
    vector = ','.join(str(random.random()) for _ in range(dims))
    data.append((primary, f"[{vector}]"))

conn.executemany("""

print(conn.execute("SELECT COUNT(*) FROM vectors").fetchall())
print(conn.execute("SELECT * FROM vectors").fetchall())

In this program, count(*) returns 0, even though the table has 10 rows.
If you comment out the 'CREATE INDEX' line, the correct answer of 10 is given.
