### Issue description

When doing operations (`begin_complex_operation` and `end_complex_operation`) with multiple selections in TextEdit, some of these selections don't revert upon undo. This behavior is affects some of script editor's operations, like duplicate selection and delete lines.

### Steps to reproduce

Open script editor, make multiple selections. Keep in mind what you have selected. Do duplicate selection (ctrl+shift+D). Undo (ctrl+Z). Compare the result to what you remember.

### Minimal reproduction project

return menu && menu->is_visible();

void TextEdit::menu_option(int p_option) {
	switch (p_option) {
		case MENU_CUT: {
			cut();
		} break;
		case MENU_COPY: {
			copy();
		} break;
		case MENU_PASTE: {
			paste();
		} break;
		case MENU_CLEAR: {
			if (editable) {
				clear();
			}
		} break;
		case MENU_SELECT_ALL: {
			select_all();
		} break;
		case MENU_UNDO: {
			undo();
		} break;
		case MENU_REDO: {
			redo();
		} break;
		case MENU_DIR_INHERITED: {
			set_text_direction(TEXT_DIRECTION_INHERITED);
