Table API Filesystem connector with 'raw' format repeats last line

When using the Filesystem connector with 'raw' format to read text data that contains new lines, a row is returned for every line, but always contains the contents of the last line.

For example, with the following file.

line 1
line 2
line 3

And table definition

create TABLE MyRawTable (
`doc` string,
) WITH (
'path' = 'file:///path/to/data',
'format' = 'raw',
'connector' = 'filesystem'
);

Selecting `*` from the table produces three rows all with "line 3" for `doc`.
