The same effect happens with changed in vertical text-align. When switched to center, the text object size decreases. Set back to top or bottom will increase the size. But this effect happens only once. If either horizontal or vertical text-align is center, the object size changes. Setting both attributes to center will not decrease the size further.

It appears the Engraved effect needs the room to display the effect, since the bottom line and right line extends leftwards and upwards above the text.
