Alexey pointed out something and we did a bit of research:

    1) The initial double click uses a different code path than extending the
selection does. They should use the same code path.

    2) The initial double click code path treats these characters inside
otherwise-alphabetical words as part of a single word. The selection extending
code does not.

    3) The Unicode Text Segmentation document has the following to say about
this:

    'To allow acronyms like “U.S.A.”, a tailoring may include U+002E full stop
in ExtendNumLet.'

Our current guess is that the initial double click code path ends up using the
word algorithm with a tailoring that includes the full stop character (period)
in this fashion.
