Bug: Overlapping Mark Nodes and Link Nodes

Lexical version: v0.5.2 - latest

## Steps To Reproduce
Issue when overlapping mark nodes and link nodes
1. If a link element already exists, wrapping a mark node over it will remove the link styling. The mark node range must be the same as the link node range. Basically adding a mark from where the link starts until where the link ends. (anchor.offset and focus.offset).
2. Wrapping half of the linked word with a mark node, will wrap the entire link in a mark node.
3. Creating a link over a text node and a mark node will duplicate/split the link node in two halves. I’ve added a couple screenshots. You will notice the link duplication in the tree view.

## The current behavior
1) Link node styling disappears
2) Wraps entire link with mark node
3) Duplicates link node
## The expected behavior
1) Link styling should remain visible
2) Should only wrap selected text with mark node
3) Should be same link node
