I have a Page A and Page B. Page A has a custom URL alias (/important-url.html). When switching the location of A and B, neither A nor B has the URL alias on it. In the database, there is still a reference from the URL to Node A and it is still working, but the backend doesn't show it.

Steps to reproduce:
1. Create two Landing Pages and name it "page A" and "page B".
2. Add some custom URL alias to "page A" for instance "custom-url".
3. Enter the Locations tab under page A and perform "Location Content Swap" selecting page B.

Since the redirection works fine, the custom URL alias should be visible under tab "URL" of page B.
