Description

This PR fixes a docstring inconsistency in Progress.reset() regarding the
visible parameter.

The docstring previously stated that visible defaults to True, but the
actual behavior preserves the existing visibility unless visible is
explicitly provided.

This change updates the documentation to reflect the current and intended
behavior without modifying runtime logic.

Fixes #3834
