I failed to make blocks ordering with BlockManager

[sergeynilov]

Using grapesjs with custom blocks I need

1. Collapse all, but extend only 1 block
2. to order them .
   I managed to make point 1), but searching for decision of point2) I found this branch :
   How to reorder BlockManager Blocks? #780

and I do it as with timer:

        let has_opened_block= false
        setTimeout(() => {
            console.log('setTimeout::')
            var closedBlocks = ['Templates', 'Blocks', 'Images', 'Basic', 'Extra', 'forms'];  // I need to collapse these blocks and move them to the bottom


            gjsEditor.Blocks.getCategories().forEach(ct => {

                ct.set('open', false);
                if(!has_opened_block) {  // to open only 1st block which is not in closedBlocks                    
                    if (!closedBlocks.includes(ct.id)) {
                        has_opened_block = true
                        ct.set('open', true);
                    }
                }
            });



            const bm = gjsEditor.BlockManager;
            var blocksToRender= [ // I want to see these blocks at top
                bm.get('h2'),
                bm.get('d5'),
                bm.get('f4')
            ]
            for (var i=0; i< closedBlocks.length;i++) { // I want to see all blocks which are not in blocksToRender at bottom
                blocksToRender[blocksToRender.length]= bm.get(closedBlocks[i])
            }
            bm.render( blocksToRender )



        }, 8000)

But as result I see 9 blocks, but which looks like empty : https://prnt.sc/86w-dqziZakn

Also I can not drag and drop content of these blocks - nothing is dropped. ,

What is wrong in my blocks ordering ?

Thanks!

Making some additive tests I see that I need to change ordering of Blocks=>Categories,
but in the mentioned link
#780
example :

const bm = editor.BlockManager;
bm.render([
	bm.get('column3'), 
	bm.get('column2'), 
	bm.get('column1')
]);

is different. I tried to change order of Blocks=>Categories in similar way, but failed.

I managed to get all categories with code like :

            const bm = gjsEditor.BlockManager;
            var blocksToRender= [
                bm.getCategories().get('h2'),
                bm.getCategories().get('D5'),
                bm.getCategories().get('f4')
            ]

            console.log('blocksToRender::')
            console.log(blocksToRender)

and how I see blocksToRender in browser's console : https://prnt.sc/3cVRoayuErAG
I tried to set new ordering like :

bm.getCategories().render( blocksToRender )
But got error :

Uncaught TypeError: bm.Blocks.getCategories is not a function
Not sure, if I can to change ordering of Blocks=>Categories ?
