Agenda clock-report-mode doesn't observe agenda filters

[Tory S. Anderson]

I love org-agenda-clockreport-mode . However, I have several files that include 
my work projects, and they all have my :WORK: tag on them. I want to get the 
number of hours put into :WORK: for the period and understand that the way is 
supposed to be to just filter my agenda view to be what I am interested in, 
then look at the associated clockreport at the bottom. However, the clockreport 
seems to always calculate everything, regardless of my agenda filters (showing 
time results for things NOT showing with my current filters). Looks like a bug, 
unless I misunderstood something.
