When copying a url-encoded link from the address bar in the browser in the TABernacle tool and pasting it in Wikipedia into the VE linking gadget, long links get chopped.
I suspect the chopping is caused by link length, but it cal also relate to its complexity.
The bug has been discussed in a Facebook thread https://www.facebook.com/groups/WikidataCommunity/permalink/2394273124191184/
