This works for me with Hunspell (I don't have Aspell installed), so
it's unlikely to be a problem on the Emacs side.  I'm guessing that
your Aspell is actually a MSYS2 program, not a MinGW (a.k.a. "native
Windows") program, so you have these buffering inconsistencies.

Or, if the above is not in "emacs -Q", perhaps some of your
customizations get in the way.
