2.0.0-beta.133 insertContentAt change is causing bug when inserting nodes into empty paragraphs

[Demivan]

What’s the bug you are facing?

When I try to insert nodes using insertContent into empty paragrapt only first one is inserted. Inserting next node replaces existing one.

How can we reproduce the bug on our side?

Reproduction in CodeSandbox.

1. Click "Insert Emoji"
2. First time - emoji is inserted
3. Next time - existing emoij is replaced

If you type something in the editor before clicking "Insert Emoji" it works as expected

Can you provide a CodeSandbox?

https://codesandbox.io/s/2-0-0-beta-132-kc79f 2.0.0-beta.132 - correct

What did you expect to happen?

Calling insertContent should insert content instead of replacing existing content

Anything to add? (optional)

Looks like isOnlyBlockContent is incorrect and does not check for content inside block nodes

tiptap/packages/core/src/commands/insertContentAt.ts

Lines 52 to 58 in 75e55e5

	let isOnlyBlockContent = true
	content.forEach(node => {
	isOnlyBlockContent = isOnlyBlockContent
	? node.isBlock
	: false
	})
