Closed releases not visible when using custom section filters

Hi,

We have a suite of custom reports that rely on the Release control in the custom section filter to work which has been working great (once I learnt about the ${ReleaseAndChildIds} token anyway).   However, recently we've started marking releases as Closed to prevent QA from accidentally executing against old releases but this seems to result in the closed releases not being selectable in the reporting filters.

So my questions are:

1. Are closed releases being deliberately filtered out of report filtering functionality?
2. If this is a bug what are the chances of a fix?  
3. Is there a work around? (One that ideally that doesn't involve reopening any release artifacts we want to report on, or even worse, having to hard code requirement ID's to report on historical releases)

Any guidance would be appreciated.

Regards,

Brad.
