After Update 8.7 to 8.8.4 a build is triggerd after sync without changes (Microsoft Git Provider)

I am using Microsoft Visual Studio 2015 Update 2 with the build in Microsoft Git Provider.

The git provider has a sync button which is a git push and git pull in one step shortcut.

Now I updated to gitlab omnibus package 8.8.4 and everytime I click on sync a build is triggered, even if I don't have any local changed that gets pushed to origin. This did not happen until 8.7.x

I can't tell what makes sync so special but I can't reproduce the behaviour on the command line git pull && git push

This is an undesired behaviour since it triggers unnecessary builds. Is there any change to diagnose why this would trigger a build?
