Fixed remove underlying pixels feature

[klakhov]

Motivation and context

There is a bug in remove underlying pixels feature. If we enable a feature while drawing a mask it wouldnt be applied. Only the next drawn mask will use the feature.
That happens because core config is not updated properly

How has this been tested?
