Accordion Bugs inside Widget (Gutenberg Interface)

[ntolakis]

Greetings,
I've notice that when I put some accordion blocks inside footer widget areas (Gutenberg Interface) after some period of time every element inside widgets gets vanished.

Just for a check I put inside functions.php

add_filter( 'use_widgets_block_editor', '__return_false' );

in order to check in the old widgets view if there is any content inside but nothing at all.

I've checked both debug.log and server log for any errors, nothing at all as well.

Do you have any idea of why this happening and if it can be fixed?
