wx.getMenuButtonBoundingClientRect 问题

• 当前 Bug 的表现（可附上截图）

wx.getSystemInfo({

success: e => {

this.globalData.StatusBar = e.statusBarHeight;

let custom = wx.getMenuButtonBoundingClientRect();

console.log(custom)

//this.globalData.Custom = custom;

//this.globalData.CustomBar = custom.bottom + custom.top - e.statusBarHeight;

}

})

在开发工具中提示错误，但是在真实手机预览确没有报错，请看看开发工具是不是有问题
