修改原始的undo redo逻辑, 记录每次修改前后的选区, 用于redo时选区的恢复, 替代原始的当前state的 state.selection.getBookmark

执行undo前更改选区位置, 将不会对重做后的选区造成影响

Modify undo/redo logic. Record old and new selection when doc was changed instead of state.selection.getBookmark()

Selection will not be affected by the selection changing before executing undo
