problem when multiple annotation form is opened

I recently found this problem which occurred when a user opening new annotation form (by clicking ‘add note’ button), while another annotation form is still opened somewhere in the same page.

various results have been witnessed while this problem is happening. one time the form wont save my annotation with a warning just like when I haven’t written anything inside the form’s massage textarea, one other time the annotation successfully saved while the other opened form popping up “saving” notification indefinitely (and seemingly cannot be closed unless the page is reloaded)

so here I am hoping for a workaround about this problem… like, maybe closing all other opened forms before opening a new one when clicking “add note” button ??

thank you.
