Why does fontconfig-2.10.95-11.el7.x86_64 fetch EPEL package as dependency if EPEL repository is enabled?

Issue

• Why does fontconfig-2.10.95-11.el7.x86_64 fetch EPEL package as dependency if EPEL repository is enabled?
• fontconfig-2.10.95-11.el7.x86_64 installation though doesn't fail if EPEL isn't enabled.
• See the following.
