Component methods that use context fail (antd)

[Driphter]

I'm running into an issue with using omify on Ant Design's Menu and Sider components. When I put a Menu in a Sider and click the collapse icon I get the following exception:

Uncaught TypeError: Cannot read property 'siderCollapsed' of undefined

Which is coming from here:

// ...
  componentWillReceiveProps(nextProps, nextContext) {
    if (this.props.mode === 'inline' &&
        nextProps.mode !== 'inline') {
      this.switchModeFromInline = true;
    }
    if ((nextProps.inlineCollapsed && !this.props.inlineCollapsed) ||
        (nextContext.siderCollapsed && !this.context.siderCollapsed)) { // <-- nextContext
      this.switchModeFromInline = !!this.state.openKeys.length;         //     is null
      this.inlineOpenKeys = this.state.openKeys;
      this.handleOpenChange([]);
}
// ...

I tried adding the context parameter to the relevant methods in omify.core/make-reshape-map and was greeted by Om with this:

Assert failed: Invalid signature for componentWillReceiveProps got [this_12431 next-props__11991__auto__ next-context__11992__auto__], need [this next-props] (= (count sig') (count sig))`.
