extreme file enlargement due to comments

Hello everyone, I noticed such a problem: after hiding comments in a document using code, the file size increases tenfold!

function Hide() {
	this.delay = true;
	this.syncAnnotScan();
	var annots = this.getAnnots();
	if (annots==null || annots.length==0) {
	app.alert("there are no comments in this document", 1);
	return;}
	for (var i=annots.length-1; i>=0; i--) {
	annots[i].setProps({readOnly: false, lock: false});
	annots[i].hidden = true;}
	this.delay = false;
	app.alert("all comments hide",3);
}

After optimizing(File - Save as Other - Optimizide PDF) the document, the file size returns to its original size, but after displaying comments and saving, it again grows in size by + 3 MB, and so on each time after the hide/show/save cycle.

How to solve this problem? add file optimization to the main code? Or is there an option in the program settings that will clear this automatically?
