Steps to reproduce:
- write text (e.g., "backlog")
- select text
- hit ctl-k
- paste in an internal link - e.g., https://en.wikipedia.org/wiki/Wikipedia:Contribution_Team/Backlogs
- get switched to the "external link" "tab"*
- dialog realizes it is a link to the same wiki I'm already on, treats it as an internal link.
- put tab in quotes because it looks like no other tab I've ever encountered; not sure what to call it.
