"Select in Zotero" functionality doesn't work properly for documents with many references

[rmzelle]

Per https://forums.zotero.org/discussion/84241/zotero-select-links-not-working-with-many-items, there seems to a Windows-specific issue where Zotero select links don't work if they contain more than approximately 220 items.

With Firefox, items are selected up to this limit, while with Google Chrome, the item selection stops working altogether. It appears that the Zotero select URL is somehow truncated by the browser/system before it is registered by Zotero.

Users can currently work around this limitation by dividing Word documents into smaller ones, so that each smaller file stays under this limit. Or they can find a macOS or Linux system. On the ref-extractor side, we could also automatically generate multiple Zotero select links if the detected system is Windows, and over 220 items are extracted.
