I think it makes sense too for regular text.

In version 0.47, whenever you create regular text, the anchor is fixed, and the inserted text always goes to the right, and then the next lines go down, so the anchor finally gets set at the bottom of the top line of text, close to the top-left corner.

This behaviour has changed for 0.48 so when the text is horizontally-centered, the anchor will be centered too, and the same for right alignment (the anchor is set in the right bottom of the first line of text).

I would expect a similar behaviour for vertical alignment, so the anchor will be set at the top, the vertical center, or the bottom of the text, so whenever new text is added, the block of text grows to the top (when bottom-aligned), or grows to the top and bottom at the same time (vertically-centered).
