Pasting inline text into a link splits the link apart

[mkevins]

Describe the bug

When pasting text in the middle of a link, the link is split (pasted text is not part of the link).

This makes it impossible to quickly change the link text via copy/paste.

Steps to reproduce

1. Select some text and create a link.
2. Copy some small inline text.
3. Place cursor within the link and paste.

Expected behavior:

Pasted text becomes part of the link.

Actual behavior:

Pasted text is not part of the link, and the link is split in two pieces.
