Help to understand version tracking

[Santiago Vila <sanvila@debian.org>]

Dear Release Managers and BTS admins:

I'd like to know if there is any special way to report a bug
so that version tracking works. See this for example:

https://bugs.debian.org/cgi-bin/pkgreport.cgi?src=uglifyjs

The top 3 bugs in the page are really the same, but they do not appear here:

https://udd.debian.org/bugs/?release=sid&ftbfs=only&merged=ign&fnewerval=7&flastmodval=7&rc=1&sortby=source&sorto=asc&format=json#results

Is this expected because it's a key package? (I hope not!)

Thanks.
