Specifying Splitter Side Animation does not work in 2.5.2

I’m trying to use the different splitter side animations in Onsen 2.5.2. Running in Chrome Version 60.0.3112.90, I get the following console error:

onsenui.js:731 Uncaught (in promise) TypeError: Invalid value used as weak map key
    at WeakMap.set (native)

    at Object.setValueForAttribute (https://127-0-0-1.collobos.net:8080/app.js:21869:13)

I used it like this:

<SplitterSide
    style={
    {
        borderRight: '1px solid #cccccc'
    }}
    side='left'
    animation='push'
    width={300}
    collapse={false}
    isOpen={this.props.sideMenu.open}
    onClose={ () =>
    {
       this.props.hideMenu();
    }}
>

I noticed that it doesn’t seem to work in the online demos either.
