Possible memory leak when quickly unselecting a feature

[Niicck]

When you quickly select and unselect a map feature (crossing or camera), we get this error message:

    in EnhancedLayer (created by Context.Consumer)
    in MappedComponent (at SelectedFeatureContainer.js:111)
    in div (at SelectedFeatureContainer.js:110)```

Every click on a feature triggers 2 render cycles. If you click the feature again before the first render cycle finishes, then you get that error. It might not matter, but I wanted to make a note of it.
