linkField: Setting path manually in dropdown list not working

Steps to reproduce

1.  Use a linkField or pageLinkField
2.  Try to set manually a path in the link, for example, '/travel'
3. The values shown in the dropdown are not ordered correctly as the first result should be just the '/travel' page (if you scroll down you should be able to see it at the bottom)
4. It is not possible to save the manually entered value either by pressing enter on your keyboard or clicking outside of the link field with your mouse. The first value in the dropdown list is always selected if you do that. It is not possible to save the value unless it's selected in the dropdown list.

This works as expected with UI5 in the old pages app.

The customer that reported this issue has many pages and they are unable to find the relevant one or enter manually the one they'd like.

Expected results

The customer should be able to enter the path manually and save it + the entered value should be the first option we offer.

Actual results

It is not possible to save the value unless it's selected in the dropdown.
