Indent EncodeOption ignored when encoding ast.Node

[braydonk]

Describe the bug
It seems that if I'm using an encoder to encode a ast.Node, the Indent EncodeOption is ignored in favour of the original indent of the node. Is there another way to change the indentation of the node on encode?

To Reproduce

Expected behavior
I expected, given the indent option with a value of 4, to receive a 4-space indented yaml result.
