on-change microflow with pop-up page keeps a page-open state in memory

[poolauto]

I created a page with 2 times the autocomplete widget in it.
Now, when I open a pop-up page with a no-results microflow to create a new record, add the record, save and close the pop-up page, de widget keeps a page-open state in memory. When I used for both autocomplete widgets the no-result microflow with an open popup page this happens: I have to push 3 times the save and close button on the main page.
