Work Sub-Filter can't be saved when the string is 273 chars or more.

This works as a Sub-Filter:
((fixVersion in unreleasedVersions() AND fixVersion != "Facelift Kurios" AND fixVersion != "Facelift adresshantering" AND fixVersion != "Future version") OR fixVersion is EMPTY) AND (resolution != "Won't Fix" or resolution is empty)

But not this:
((fixVersion in unreleasedVersions() AND fixVersion Unable to render embedded object: File (= "Facelift Kurios" AND fixVersion != "Facelift adresshantering" AND fixVersion != "Future version" and fixVersion) not found.="Facelift Drag and Drop") OR fixVersion is EMPTY) AND (resolution != "Won't Fix" or resolution is empty)
