Duplicate to multiple pages - Bug

[duruyoungcr]

Using the Duplicate to multiple pages doesn't close the modal when only One page is selected, but it does do the copying expected. Also if you select some pages do the duplication but do not close the component, when next you copy the previously selected pages would also be duplicated to. It seems the selectedPages only resets when the component unmounts.

Also, a good addition to the modal would be a search input for the pages. So it's easier to find pages.
