I've seen it was addressed in:
ecd52d7

but isn't yet on any release

[metasyn]

We're running into this as well, and are installing ecd52d7 now via git, but would be great to see this added to a versioned release

Thanks for identifying it fruch

If you update your dependencies, it's fine, no need for a git version. But we probably should try to get a release out at some point.
