is-numeric in Zotero 4 and 5
I've only noticed this since switching from Zotero 4 to 5: Zotero 4 treated variables like "6.1" as numeric (in an is-numeric conditional). At least that is what my "test suite" PDFs generated with Zotero 4.x show. But Zotero 5 does not do this anymore. It this intended?
