Found when testing T303985. The testing was done on cswiki betalabs and testwiki - the issue might be specific to those testing environments. This issue is about the task counter on the SE module on Special:Homepage and on the post-edit dialog.
The underlying issue - the SE (non-structured tasks) are not removed from the feed even if a user has edited it.
- In SE module select two task filters - one for a structured task (add image or add link) and another one for a non-structured task.
- Go to a suggested article and make an edit. The counter in the post-edit dialog will display correct or incorrect count depending which type of task was edited:
- if an edit was made on a structured task, the structured edit task will be removed from the feed. The counter will show the number suggested tasks left minus one (CORRECT)
- if an edit was made on a non-structured task, the article is left in the feed. The total count of available articles will not be changed, but the actual count (when flipping through the tasks) will be minus one.
Post-edit dialog shows that there are total 11 tasks, but the arrow is inactive  | The end of the feed is reached (the warning is displayed), but the counter shows that there is another task  |
Notes:
- This is a known issue. The impact is more noticeable since the post-edit dialog presents the unchanged count of suggested tasks.
- The counter behavior (the mismatch between the total count and what's actually available) might be viewed not only as confusing but as an un-addressed bug.
