An R2018+ MTEXT can carry an embedded object (group 101) in which 10 is the
X-axis direction and 11 the insertion point. AutoCAD writes one for MTEXT with
column settings, and so does the DWG bridge. The reader took the first group 11
anywhere in the entity as the direction, so such text turned towards its own
insertion point. Read 11/21 and 50 from the MTEXT's own groups only.
