I'm not aware of any straightforward way. You could create a temporary layer (using memory provider) and put the selected features into it. If the temporary layer will be placed on top of the original layer, the user will always see the selected features. If using new symbology, you could implement a custom renderer which would delay rendering of the selected features and render them at last in stopRender() method.
