Edit Permission page doesn't respond when it has 100K related builds

This issue is relevant only for Artifactory 6.X and doesn't happen on 7.X

Description: Trying to edit a permission target that is associated to 100K builds or more, causing the browser tab to become unresponsive.
As seen in the screenshot below, it already fetched all the information, but UI is failing to load and just hangs (sometimes it eventually loads after a long time).

Steps to reproduce:
I used the script below which uses JFrog CLI:

#!/bin/bash
for i in {1..120000}
do
   ./jfrog rt bce build-$i-name 1
   ./jfrog rt bp build-$i-name 1
done

Once done, simply navigate to the Artifactory UI and try to open a build that has "Any Build" association.
