Setup:
*Using Zotero v5.0beta on Firefox, Windows 10
*Performed a search on EBSCOhost

Summary:
*Zotero will not consistently import all displayed results
*Zotero does not consistently download the fulltext pdf

Situation:
I have performed a search on EBSCOhost, for which there are 60 results. I arrived at the search from a permalink. I am trying to import to Zotero all the results displayed on the screen using the "import to folder" function. However, regardless of how many results I have displayed on the screen (e.g. 5, 10, 20, 50), Zotero does not always import all the results. On a given page that shows 5 results, sometimes it will import all results, sometimes only 4, sometimes only 3, etc. This behavior persists even if I stay on the same page and perform the import multiple times. Furthermore, Zotero does not always import the pdf attached to a given reference. Sometimes if it fails to download the pdf, if I immediately run the import again, it will then successfully download the pdf.
