WYISWG editor do not work inside nested group on some instances

Hello Peter,

Please enable cloneable for the WYSIWYG field and enable the option "Clone empty start" then check the issue again. Let me know how it goes.

Hello,

I've escalated this issue to the development team for fixing. It will be included in the next update of our plugin.

Thank you.

Hello,

Can you please export the field group to a JSON file and share it here? I will check the post field on my demo site. Following the documentation https://docs.metabox.io/extensions/meta-box-builder/#export--import

Hello Peter,

I see the slowdown issue of the field group when having more custom fields on the editing page. I will forward the issue to the development team to check it and improve the performance of the WYSIWYG field in the cloneable group.

I found a temporary solution, but it slows down the editing page. It turns out that the ids for texarea for wysiwig are not created correctly.

<textarea class="rwmb-wysiwyg wp-editor-area valid" rows="20" autocomplete="off" cols="40" name="sw_c_row[6][sw_c_col][1][sw_c_content]" id="sw_c_col_sw_c_content" aria-invalid="false"><div class="h-4 h-lg-1">34 lata wyzwań nauczyły nas, jak być lepszą organizacją, budować silną markę i wspierać naszych partnerów. Poznaj nasza historię.</div></textarea>

In this case I have a clonable group in a clonable group. The textarea gets an id without the name of the parent group and without its sequence number. This creates multiple textarea with the same id, from which wysiwyg is called. Since multiple textarea have the same id, wysiwyg does not start fully for them.

I solved this problem by modifying the wysiwyg.js script for the meta-box.
/meta-box/js/wysiwyg.js
In the file for the transform() function I added a line so that the isInBlock variable always has the value true, which changes the id to unique.

function transform() {
		var $this = $( this ),
			$wrapper = $this.closest( '.wp-editor-wrap' ),
			id = $this.attr( 'id' ),
			isInBlock = $this.closest( '.wp-block, .components-panel' ).length > 0;
			
        isInBlock=true;
		// Update the ID attribute if the editor is in a new block.
		if ( isInBlock ) {
			id = id + '_' + rwmb.uniqid();
			$this.attr( 'id', id );
		}
...

and in the load function I changed the re-render condition to fire not only for Gutenberg

	// Force re-render editors in Gutenberg. Use setTimeOut to run after all other code. Bug occurs in WP 5.6.
		if ( rwmb.isGutenberg ) {
			setTimeout( () => $editors.each( transform ), 200 );
		}else{
			setTimeout( () => $editors.each( transform ), 20 );
		}

unfortunately this forces a re-render for each wysiwyg, which increases the time it takes to load them. But at least it works until a better solution is found.

Sorry to push this, but is there any ETA on when the update will be pushed out?
