+I've hit this bug with an inline-table and 3.20190228-1 (so: patch applied), with the following definition
+
+ [[\!table class=fullwidth_table delimiter=" " data="""
+
+ Number Title Own? Read?
+ I (HB1), 70 (PB1), 5 (PB50) Dune O ✓"""]]
+
+I'm going to attempt to work around it by moving to an external CSV. — [[Jon]]

+> I could't reproduce this with `libtext-csv-perl_2.00-1` and
