This is all we need to know, so this did work.

It isn't supposed to.

Now invoke aspell from your shell prompt exactly as shown above, i.e.

  /usr/bin/aspell -a -m -d en --encoding=utf-8

Aspell will then wait for input from standard input.  Type the string
you see in the ispell.el's debug buffer.  E.g., with hunspell, when I
invoke the command ispell-buffer-with-debug on your LaTeX file, I see
this in the ispell debug buffer:

  ispell-region: string pos (29->53), eol: 53, [in-comment]: [nil], [add-comment]: [nil], [string]: [^\autoref{alice} envolope
]

which tells me that the string it will pass to the speller is
"^\autoref{alice} envolope" (without the quotes).  So type this string
and hit [Enter].  Then see what aspell outputs in return.

Once again, please CC the bug address so that this discussion gets
recorded there.

Thanks.
