how restore the default displaystyle (like display open the imodel file ) after use Viewport.overrideDisplayStyle ！

[pmconne]

// Save a copy of the original style
const oldStyle = viewport.displayStyle.clone();
// Override the style
viewport.overrideDisplayStyle({ /* whatever */ });
// Some time later, restore the original style
viewport.displayStyle = oldStyle;
