Emits warning about prop 'initiated'

[jeghers]

When creating this component with any types of children, the following warning message is emitted to the browser console:

Warning: Received `true` for a non-boolean attribute `initiated`.

If you want to write it to the DOM, pass a string instead: initiated="true" or initiated={value.toString()}.
    in div (created by ContainerDimensions)
    in ContainerDimensions (created by Card)
    in div (created by Card)
    in div (created by Card)
     ... etc etc etc ...

I cannot find any way to stop the warning message from being sent to the console.
