Cut and Paste (CMD+X -> CMD+P) does not restore pasted custom block with it's data

[natterstefan]

Issue

In our app we have lot's of "Enrichments". They can have several different types (eg. image, audio, ...). Because of legacy reasons we cannot simply render a <img> or <audio> tag.

Nevertheless, I was able to register and add custom tools (with React support) for each enrichment type. BUT when one moves them with CMD+X and CMD+P they are added as a simple paragraph or when the block is detected without data.

FTR:

• I am not sure if the pasteConfig is correct, as I render a div with some other elements inside. Not sure what's the correct pattern/tag then.
• Not sure how to make sure onPaste receives existing data from the pasted block as well.

Expected outcome

I can copy and paste existing blocks with all it's data within the Editor container.

Environment

• React: "react": "16.11.0"
• Editorjs: "@editorjs/editorjs": "2.15.1"

i am getting a number in the text object of theresult , if i copy and paste text it puts numbers as shown below :

{
    "time" : 1574519623180,
    "blocks" : [
        {
            "type" : "paragraph",
            "data" : {
                "text" : "2"
            }
        },
        {
            "type" : "paragraph",
            "data" : {
                "text" : "2"
            }
        }
    ],
    "version" : "2.15.1"
}

We can add special formatting to the copied text that will allow us to determine block types on pasting. But in this case, copying/pasting to the other regular text documents will contain unwanted extra symbols.

We will research this case and find a solution. Maybe this can be done by modifying the DataTransfer object by adding our own mime-type. Or we can provide options on how you want to copy selected fragment: as simple text or as Editorjs format.
