PagePreviews

There is a link here to:

• Example (one)
• Example (two)

Timeline:

• Create Example (one) as regular page, and create Example (two) as redirect to Example (one).
  • At this time, hovering the above links both display the preview of "Example (one)".
• Renamed page Example (one) to Example (two) over a redirect. This internally results in a deletion of Example (two).
  • At this time, hovering the above links both display the preview of "Example (two)". When hovering the link for "one", the Network inspector shows RESTBase as performing a 302 redirect for the preview of "one" to "two". Still working as expected.
• Made an edit to page at Example (two).
• Made an edit to redirect at Example (one). This means in the future, unlike originally, MediaWiki will not silently delete Example (one), because it has more than one edit in its history.
• Renamed page Example (two) back to Example (one). During the move, unlike originally, a prompt appeared saying "The destination page "Example (one)" already exists. Do you want to delete it to make way for the move?". Answered with "Yes, delete the page".
  • At this time, hovering the above links both display the preview of "Example (one)". When hovering the link for "two", the Network inspector shows RESTBase as performing a 302 redirect for the preview of "two" to "one". Still working as expected.
