### 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

		if (has_selection(i)) {
			continue;
		}
		int first_vis_line = get_first_visible_line();
		if (get_caret_line(i) < first_vis_line || (get_caret_line(i) == first_vis_line && get_caret_wrap_index(i) < first_visible_line_wrap_ofs)) {
			set_caret_line(first_vis_line, false, false, first_visible_line_wrap_ofs, i);
