Struct UndoHistoryStep 

pub struct UndoHistoryStep {
    pub group_id: usize,
    pub edits: Vec<UndoHistoryTextEdit>,
    pub before_selection: UndoHistorySelectionSet,
    pub after_selection: UndoHistorySelectionSet,
}

A single undo/redo step in a persisted history snapshot.

after_selection: UndoHistorySelectionSet

Selection set snapshot after applying this step.
