alternatively could looks for the intersecting bounding boxes of all targets

Both work well... but without any depth/thickness the chance of intersection are null...
extruding the plane to a volume on a known axis, e.g z here (no rotation) is trivial but limiting.
Could rely on the bounding sphere instead but not ideal when text is beside other pieces of text
Note that in practice we plan to bring geometry with the text, a la Scratch, to showcase grammar and potential to combine.
Consequently those problems would probably go away by intersecting with that geometry instead.
That still means an efficient solution, e.g convex hull or BVH
