Multiple lines of text produce incorrect Gerbers.

Multiple lines of text on silk produce Gerbers inconsistent with design render. It looks as if the placement of text on these layers is aligned to the center of the block of text whereas the Gerber output is aligned to the center of the first line of text. Please see attached image for side-by-side.

Gerbers generated via plot dialogue, mm units, use auxiliary axis as origin.
