Summary
Fixes task_id duplication when unmapping a MappedOperator within a TaskGroup. Previously, task IDs would get double-prefixed (e.g.,
tg1.tg1.mapped_taskinstead oftg1.mapped_task).Problem
When
MappedOperator.unmap()is called, it passes the already-prefixed task_id toBaseOperator.__init__, which applies the prefix again viatask_group.child_id().closes: #52334
Solution
Check if task_id already contains the task group prefix before passing to BaseOperator, preventing double prefixing.
Testing
Added test
test_mapped_operator_in_task_group_no_duplicate_prefixto verify the fix. All existing tests pass.
