Read ARFF operator does not provide attribute names to subsequent operators

When I connect the output of "Read ARFF" operator to "Select Attributes" operator, the select list in "Select Attributes" operator does not get populated by column names. This behaviour is inconsistent with behaviour of other readers like csv or database.
Note: The column names do not get populated even after running the whole process.
Workaround: Write the column names into the select lists.

confirmed bug in meta data propagation in Read ARFF operator. Thanks for reporting.

Workaround from engineering:
"You can add a breakpointer on Read ARFF, run into the breakpoint, edit the following operators that now do have meta data, and run the remainder of the process as a workaround."
