Steps to reproduce:
- go to your homepage (tested on huwiki)
- observe you get a large number of suggested edits
- start clicking through the results with the "next" arrow
- observe that after a while the total task count changes to something like your current position plus ten or fifteen (and you will get the no more results page when you get there).
It happens randomly, but very frequently. Feels like a JS race condition in handling the growthtasks API call. The number where it happens is different on every try.
Re-checked on wmf.8 (as part of reviewing open issues for Create Task T379124: Suggested Edits: Newcomer Tasks count QA)
Summary:
(1) the issue is easily reproducible on frwiki and eswiki ( on dewiki the issue is not that easy to reproduce) with the following steps
- on Special:Homepage do not select any topics
- select Add link (a structured task) task type
- click on the arrow button (doesn't matter how fast or slow is clicked; if you want to go fast, mouse-focus on the arrow and click the space bar to go fast)
- past 15th task, the initial counter number will change a different number, usually to less than 30
(2) huwiki wmf.8 - the issue is still not reproducible for me; doesn't matter how fast the arrow button is clicked
(3) Selecting different task types or selecting all topics/some of the topics do not trigger the issue. It seems that the issue is isolated to the selection of Add link structured task.
