Cannot add list item when there's a link at the end

[swissspidy]

Describe the bug

If a list item ends with a link you cannot press enter to add a new list item. You first have to write another letter before you can press enter.

To Reproduce
Steps to reproduce the behavior:

1. Create a new list
2. Add a new list item and turn the last word into a link
3. Try to hit enter
4. Notice that nothing happens

Expected behavior
A new list item is created when pressing enter, no matter what the list looks like.

Screenshots

Here's where I tried to hit enter (after the @wpzurich link) — and yes, I was not inside the link.

Desktop:

Chrome 70 on macOS

Additional context
WordPress 5.0-beta3-43876

Tested and confirmed using WordPress 4.9.8 and Gutenberg 4.2.0 using Firefox 63.0.1 on macOS 10.13.6 and noting an error from the console that pops up as soon as I press enter with the caret placed outside the inline boundary for the link as the last thing in the last item of a bulleted list:

TypeError: t is undefined

This appears to be fixed in 4.4.0
