Can we deprecate this for the future in the hope that it gets fixed?
You could put version <= 5.0.1 or something.

[boliu, 2015/02/10 21:03:56]

Ehh...currently that check would be >= 5.0.2 as this bug is a regression in a
future version :(

[boliu, 2015/02/10 21:25:51]

Oops, should be:
"> 5.0.2"

[vmiura, 2015/02/11 05:07:43]

Yeah, it's actually a regression from > 5.0.2.

I think once we have an idea of what version ships, and what version it would be
fixed in then we can add the filter <= N case.
