From b4dae6c2a3ed843865d5bbd10f25ea5086167e1e Mon Sep 17 00:00:00 2001

Subject: [PATCH] allow window_decorations to work with config_builder

We need to manually convert to string, as the default ToDynamic
impl encodes the underlying bits value from the bitfield and
that doesn't round trip with the try_from String impl
