Task Instances not correctly displayed in task group header in grid view

Apache Airflow version

main (development)

If "Other Airflow 2 version" selected, which one?

What happened?

If I take a look to a task group the header is showing the task summaries of states, but I see actually two "bugs":

1. The task instance summary shows the Dag defined task counts as "count"/total but is a mapped task is in the task group the mapping is not respected. For example the run here mapped 40 tasks but only "3" are shown as success:

Mapped task details:

2. Also taking a closer look to ^^^ it is showing the total of "3" tasks (and not 42) but the task isnatnce list shows no results (translated: "Kein Element vom Typ Task Instanzen gefunden")

What you think should happen instead?

1. The task count should show the number of task instances in the run including any mapped total and not only the "abstract" task count from Dag structure.
2. The lower part of the details panel should list all tasks in the task group

How to reproduce

Start current main from breeze and run the "integration_test.py" Dag from Edge, set any number of task mapping on trigger and inspect the task group of the mapped task in grid view

would like to give a try, thanks @jscheffl

2- is caused by prefix_group_id=False. This will remove the prefix from the Tis display name, and therefore the match won't work anymore. Which respects the display name search. Instead we should probably implement proper task_group filtering feature on the API side.
