I confirmed this behavior.

I got the following completion result while testing your above example:

$\biol$


And the C-M-i is bound to flyspell-auto-correct-word in my case as shown below:

```C-h k C-M-i RET
flyspell-auto-correct-word is an interactive and compiled function
defined in flyspell.el.gz.

Signature
(flyspell-auto-correct-word)

Documentation
Correct the current word.

This command proposes various successive corrections for the
current word.  If invoked repeatedly on the same position, it
cycles through the possible corrections of the current word.

See flyspell-get-word for details of how this finds the word to
spell-check.

It has been enabled in my case.
