Paragraph: paste contents at cursor point rather than as new blocks

[annezazu]

Hat tip @richtabor for the text and video: When selecting, copying, and pasting, across more than one paragraph block, the selected contents are not pasted at the cursor point. Unexpectedly, the contents are pasted as new blocks.

The expectation is that one pastes the copied contents of more than one block, right where the cursor is. The contents should inherit the attributes of the pasted-in paragraph.

cc @ellatrix for consideration as you weave your way through writing flow issues.

Could you elaborate more on what you're expecting? Yes, currently, for multiple blocks, we split the paragraph into two at the caret, and then insert the pasted blocks in between.

Do you expect all content to be inlined? Do you expect only the first pasted block to be merged with the first split block, and then last pasted block to be merged with the end of the split?

More visually:

This is your clipboard:

Paragraph one

Paragraph two

Paragraph three

This is your content with a caret:

Existing‸ post.

What do you expect when you paste the two paragraphs?

What happens now:

Existing

Paragraph one

Paragraph two

Paragraph three

 post.

Is this what you expect?

ExistingParagraph one

Paragraph two

Paragraph three post.

Is this what you expect?

Yes. :)

@richtabor What if you replace Paragraph one with a heading Heading one? What should happen? My current PR does this:

Existing

**Heading one**

Paragraph two

Paragraph three post.

Into

If pasting into an existing paragraph block, I'd expect the new contents to inherit the new block:

<p>Existing‸ post.</p>

with a clipboard of

<h2>Heading one</h2>
<p>Paragraph two</p>
<p>Paragraph three.</p>

to be

<p>ExisitingHeading one post.</p>
<p>Paragraph two</p>
<p>Paragraph three.</p>

Replace

If replacing an existing paragraph block entirely, I'd expect the origin contents to remain in as intended. Below I'm emulating selection on the entire first paragraph block.

[<p>Existing post.</p>]

with a clipboard of

<h2>Heading one</h2>
<p>Paragraph two</p>
<p>Paragraph three.</p>

to be

<h2>Heading one</h2>
<p>Paragraph two</p>
<p>Paragraph three.</p>
