Link Plugin: Dropping two subsequent content links will merge them, ignoring target of second

[mmichaelis]

Describe the bug

When dropping two (or more links) one after another at the end of the text, both links will be merged into one having only one target.

To Reproduce

Steps to reproduce the behavior:

1. Open Example App
2. Empty Content (easier to reproduce)
3. Open Drag Examples
4. Drag first content
5. Drag second content "at the end", thus, the mouse cursor far to the right
6. See error

Expected Behavior

A second link is created with its text added right behind the previous link. Both parts have a different link target.

Actual Behavior

Text of the second link is written, but the attributes, especially the link's target, is only taken from the first dropped link.
