Research direction
Reproduce the problem using the linked StackBlitz, starting with app/tab-group-dynamic-example.ts and the steps for inserting a tab at the beginning. Trace how the dynamic mat-tab group handles selecting the newly inserted first tab. Done means selecting the checkbox and clicking “Add new tab” selects the first tab immediately.
