Accessing "Latest data" from the "Links" section of the "Latest 20 issues popup" doesn't include "groupid=XXX" in the link, hence I see the list af all hosts within latest issues when clicking on it.
For example, if I:

• go to "Latest 20 issues" panel
• click on an hostname
• click on "Latest data" under "Links"

This behaved as expected in 1.8 (i saw the latest data for the selected host), since the link included the "groupid" parameter
