Research direction
Investigate the MudTimePicker component's handling of keyboard events, specifically the Tab key. Look at the component's onblur or onkeydown event handlers in the source code to understand why the selected time is not being committed when Tab is pressed. Compare with similar components like MudTextField to see how they handle tab navigation. The issue likely requires modifying the event propagation or manually triggering value update on tab.
