Words in aspell's personal dictionary can't be used by ispell.

[hongyi-zhao]

On Ubuntu 20.04, I'm using "/usr/bin/aspell" as the value of ispell-program-name for Emacs. I've a personal dictionary which has the following contents:

$ cat ~/.aspell.en.pws 
personal_ws-1.1 en 2 
Telegram
destigmatize

But company-ispell can't give the completion hint for the word destigmatize, as shown below:

See here for the relevant discussion.

Any hints for this problem?

Based on my subsequent testing, the input part of a word must reach a minimum length threshold, say, destigma, otherwise, it won't enter into the ispell candidate list.
