If multiple filters are open, only the filter opened most recently will be active. If one filter is open for Open - Platform A - PROJECT - Bugs and for cross verification purposes another filter is subsequently opened for Open - Platform B - PROJECT - Bugs, viewing any bugs for Platform A will leave the user with no choice but to return to a list of bugs for Platform B.
