Is this defined in the specification? If not, I think you should post an issue there. Almost all window properties are writable except for just a few like top or location according to the specification.

Able to reproduce this issue on reported version 62.0.3202.89 and latest Canary 64.0.3265.0 using Windows 10, Ubuntu 14.04 and Mac 10.12.6. 

The issue is seen from M-50 (50.0.2637.0). Hence considering this issue as Non-Regression and marking it as Untriaged.

Works as intended.

Some libraries make use of the behavior, monkey-patching in their own requestAnimationFrame function to ensure their code runs before and/or after their users' rAF callbacks.
