Yarn ignoring .yarnrc in parent directories

What is the current behavior?
Yarn does not merge .yarnrc files up the file tree.

If the current behavior is a bug, please provide the steps to reproduce.

1. Create a .yarnrc in a parent directory (on Windows 10) with the following content:

version-git-tag false

2. Run .yarnrc from a child directory.
3. Note the setting is ignored.

What is the expected behavior?
.yarnrc documentation claims that config files are merged all the way up the file tree. I'd expect the output to show 'version-git-tag': false

yarn: 1.4.0
node: 9.4.0
OS: Win 10 x64 Enterprise
