Clipboard data of 'text/plain' are pasted as html?

[hata6502]

Example, paste the following plain text data

<b>bold</b>

EditorJS displays

bold

I'll write more detail soon. 😃

1. Copy <b>bold</b> as text/plain:

2. and watch dataTransfer by console.log:

(src/components/modules/paste.ts)

3. <b>bold</b> is got as text/plain:

4. but, <b>bold</b> is pasted as text/html:

I think text/plain data should be pasted as text/plain, not text/html.

For example, this matter prevents writing HTML learning article.
It may also prevent making own Raw HTML block.
