Add coverage for the interactive row reset.

The existing switcher tests do not render SwitcherItem or pass a render prop, so they cannot detect removal of the interactive borderStyle, appearance, or transparent background declarations. Add a feature or browser test that renders a clickable switcher row and checks the resulting reset.

around lines 41 - 42:
Add a feature or browser test that renders SwitcherItem through its render prop
as a clickable row and verifies the interactive row retains the borderStyle,
appearance, and transparent background reset declarations. Use the existing
switcher test setup and cover these styles on the rendered row.
