How to preserve group ownership

Question

I recently created a group called "special", added some users (including myself), and successfully created a directory where all users in the "special" group can read and write. The umasks have been changed from the default 0022 to 0002 in /etc/launchd-user.conf. Here's how I tested this:
$ mkdir myTestDir
$ ls -l | grep myTestDir
drwxrwxr-x   2 tdunlap  staff   136 Jul 25 12:13 myTestDir
$ chown :special myTestDir
$ chmod g+s myTestDir
$ ls -l | grep myTestDir
drwxrwxs-x   2 tdunlap  special   136 Jul 25 12:13 myTestDir
$ cd myTestDir
$ mkdir my2ndTestDir
$ touch myTestFile.txt
$ ls -l
drwxrwxr-x  2 tdunlap  special  68 Jul 25 12:17 my2ndTestDir
-rw-rw-r--  1 tdunlap  special   0 Jul 25 12:17 myTestFile.txt
Here we see the group and appropriate permissions are created when performing tasks on the command line. The same has been confirmed when using Finder and TextEdit.app. But I noticed an issue of the group not being preserved when I use Applications like Chrome.app and Archive Utility.app to download and unzip files, respectively. Here's what happens:
drwx------@ 4 tdunlap  staff         136 Jul 25 12:42 802.11
-rw-rw-r--@ 1 tdunlap  staff    16833611 Jul 25 12:42 802.11.zip
drwxrwxr-x  2 tdunlap  special        68 Jul 25 12:17 my2ndTestDir
-rw-rw-r--  1 tdunlap  special         0 Jul 25 12:17 myTestFile.txt
Notice the zip file I downloaded is saved with my Primary Group ID, not the group ID of the folder. And when I use the Archive Utility.app to unzip, the same thing happens. However, examine what happens when I use unzip from the command line instead of the Archive Utility.app:
$ unzip 802.11.zip
Archive:  802.11.zip
  inflating: 802.11-2012.pdf        
   creating: __MACOSX/
  inflating: __MACOSX/._802.11-2012.pdf 
  inflating: 802.11v-2011.pdf       
  inflating: __MACOSX/._802.11v-2011.pdf 
$ ls -l
total 95520
-rw-r--r--@ 1 tdunlap  special  24739306 May 21 13:54 802.11-2012.pdf
-rw-rw-r--@ 1 tdunlap  staff    16833611 Jul 25 12:42 802.11.zip
-rw-r--r--@ 1 tdunlap  special   7329554 May 21 13:47 802.11v-2011.pdf
drwxrwxr-x  4 tdunlap  special       136 Jul 25 12:40 __MACOSX
drwxrwxr-x  2 tdunlap  special        68 Jul 25 12:17 my2ndTestDir
-rw-rw-r--  1 tdunlap  special         0 Jul 25 12:17 myTestFile.txt
Once again it appears that command line tools honor the group ownership, but GUI-based apps do not.
Can anyone suggest how I can ensure attachments downloaded into this directory honor the "special" group instead of saving as "staff"? I prefer not to change the Primary Group ID for each member of the "special" group. I could also run a periodic cron job looking for "staff" group on files and/or directories then performing a chown :special on the offenders. But there must be a better way.
Any suggestions?
Thanks!

When you remove querystring , then it displays all the data, so no dynamic filter required. But with Filter it reload the filtered  data. That may be the reason for not keeping the states.
You can expand collapse the groups by using javascript code. You can either expand all rows or do some JS trick to store current expanded row state in some hidden control and re-expand them at load through you js code as explained below -
You can find image ID for the collapse-expand image (the '-' image) and can call a SP javascript function (ExpCollGroup()) to collapse/expand and loop it for all row.
$(function(){
ExpCollGroup('id..','img_...');
