Not a regression, same issue in 3.x

It indeed doesn't get written, but it also doesn't get read (tried by manually inserting a color property).

          <TremoloBar>
            <color r="0" g="0" b="255" a="255"/>
            <point time="0" pitch="0" vibrato="0"/>
            <point time="30" pitch="-100" vibrato="0"/>
            <point time="60" pitch="0" vibrato="0"/>
            </TremoloBar>
