Unknown ID Lifer at Fraser's Hill

Very fast email reply from Ronald Orenstein a wandering Naturalist from Canada who identified this as White-browed Shrike-Babbler - Female (Pteruthius flaviscapis). Thank you!.
"Which is incidentally, neither a shrike nor a babbler but, probably, a member of the New World vireo family (Vireonidae)".

This unidentified bird perched very high at Telecom Loop @ Fraser's Hill.
Still clueless after four days searching for ID. The above picture was edited with Photoshop - the branches clone out and slightly increased in green saturation.
Anyone can help me?

Pteruthius flaviscapis cameranoi - subspecies in Peninsular Malaysia and Sumatra.
