When accessing a text selection, avoid extra check for removal of oblivious text attributes to make those usable outside the context of #interactivePrintIt. Approximate slow-down is still about 2 orders of magnitude away from being noticed during user interactions (e.g. cut, copy). So, we are fine here. Empty selections (i.e. the normal blinking text cursor) are still very fast.
