There is some strange behaviour I noticed in this question. How much The Square is Swedish and Danish? . Its title is not updated after the revisions by user.
In revision 3, @AnkitSharma edited the title and the body of the question. An hour later, @Paulie_D made further edits in the body in revision 4. There was no modification to the title. Yet, the outcome after the edit kept the tile of revision 2.
Following is the screenshot of all the revisions made to the question.
Why did this happen?
