**Description:**
That is in 1.18 production wiki.
Edits made in two tabs with opening https://de.wikipedia.org/w/index.php?title=Datei:Logo_African_Pygmy_Goat.png&action=edit in both
* first edit: https://de.wikipedia.org/w/index.php?title=Datei:Logo_African_Pygmy_Goat.png&diff=99713605&oldid=99710289
* second edit: https://de.wikipedia.org/w/index.php?title=Datei:Logo_African_Pygmy_Goat.png&diff=99713610&oldid=99713605
Second edit overwrote the first edit - there must be displayed an edit conflict but it was not.
Correct and expected behavior can be observed here:
Same but edits made with https://de.wikipedia.org/w/index.php?title=Datei:Logo_African_Pygmy_Goat.png&action=edit§ion=2 (note the section param!)
*first edit: https://de.wikipedia.org/w/index.php?title=Datei:Logo_African_Pygmy_Goat.png&diff=99714085&oldid=99713610
*second edit: Result on saving the second edit: edit conflict (I had added "barfoo" at the same place where I had added "foobar" (first edit).
Another example where there was no EC displayed: https://de.wikipedia.org/w/index.php?title=Datei_Diskussion:Logo_African_Pygmy_Goat.png&diff=99711750&oldid=99711748
Also no EC displayed in MW 1.19 testwiki: https://test2.wikipedia.org/w/index.php?title=File:AaatestSonnepalmenstrand-portrait_new.jpg&diff=35606&oldid=35605
and: https://test2.wikipedia.org/w/index.php?title=File:AaatestSonnepalmenstrand-portrait_new.jpg&diff=35626&oldid=35625
Similarly no EC is shown in MW 1.19 (resulting in "overwriting" the older edit) if: a) both edits are made by the same user, b) the second edit is done via "edit" at top and not using sections.
To repeat:
* If the second edit is done with a section parameter: a EC is (correctly) detected...
* If the users making the edits are different user accounts: a EC is (correctly) detected...
