The behavior of IDM has changed throughout the years and enhancements. There is an enhancement now included within the product that allows clients to get more granular with task behavior.
Resolution 1 (For all tasks to behave the same):
Implement SwitchTabWhenInvalid property under the miscellaneous section within the management console.
Steps:
Navigate to Home > Environments > identityEnv > Advanced Settings > Miscellaneous

Resolution 2 (For specific tasks):
Set SwitchTabWhenInvalid on the task itself within the properties section.
Steps:
