There seem to be a lot of cases where users experience edit conflicts either with themselves or with others from older revisions of an article.
The generated diffs shown on these conflicts seems to only reflect the actual change that was meant to be submitted.
For a more technical background and objective data on that see T246440: High proportion of edit conflicts seem to not involve a conflicting edit and T246439: High proportion of edit conflicts seem to come from new article creation
In the original version of this ticket this was partly reproduced by doing the following:
An edit conflict when creating a new page under the following conditions:
- I am not logged in ( when I am logged in - at least this method - does not work )
- I create a new page with some random text ( do not submit yet )
- I click the save buton three times very fast ( clicking very fast only twice does not seem to be enough help )
- I get an edit conflict although it's the same user and it's identical content ( the diff is even empty here )
An edit conflict when adding a new topic to a talk page:
- I visit a random talk page ( logged in or not )
- I add a new topic by clicking on the Add topic link
- I click the save buton three times very fast ( clicking very fast only twice does not seem to be enough help )
- I get an edit conflict although it's the same user and it's identical content ( I at least get a diff although it looks weird )
