Autocomplete search input broken in latest version

[hatsumatsu]

Describe the bug
After the latest updates, the experimental autocomplete search widget to connect posts is broken. When typing in the input field, no posts are shown.

To Reproduce
Steps to reproduce the behavior:

1. Enable the experimental autocomplete inputs feature
2. Edit a post
3. Search for a post title in the connected sites
4. No posts are returned

Environment (please complete the following information):

• PHP Version 8.2
• Plugin Version 2.8.1

Fix
After some debugging it seems that in the suggest() method, query vars are retrieved from the GET object, though the autocomplete request method ist POST.

Multisite-Language-Switcher/includes/MslsMetaBox.php

Line 20 in 5e89e49

public static function suggest() {

Switching from INPUT_GET to INPUT_POST in this method fixes the bug.
