Grid pop-up of start/queue time is inconsistent

Under which category would you file this issue?

Airflow Core

Apache Airflow version

main (as of 2026-06-07)

What happened and how to reproduce it?

The current Gantt preview/popup of starting, queueing and landing times is inconsistent on main.

If you have a task that has a bit longer queue time then the popup on the queued part is printing wrong "start date".

See popup when mouse is hovering over the period of queueing:

Compared to hovering over the period of execution:

Note that the latter one is "right" and should be displayed on queued timeline as well-

What you think should happen instead?

Consistently "right" time stamps should be displayed.

Re-opening also as comment on PR:

Thanks @shashbha14 for the fix! The Start/Queued date is now correct - but I think this catched a small regression. Now the End Date is somehow "wrong". In the queued state it shows the end date of the queueing and not the end date of the task, see:
