It seems fully workable. But requires rigorous testing.
It should be reverted later.
We should not only activate alternative view on RUN if it was not activated yet, but re-activate it on all subsequent RUN actions. This commit significantly simplifies implementation. * No reliance on 'offsetParent' checking, which is a bit fragile. * Full reliance on 'preferredView' state, which can be 1 (for EGI) and 2, 3 and so on (for alternative views). We can rely on it because this state is always initialised as early as possible on client application.
…ransitions. Transitions to EGI / alt view from other EGI / alt view should not activate any other insertion points. Transition to EGI should always do nothing (besides saving new preferredView state to persistent storage). Transition to alt view should always activate it (and save preferredView state to persistent storage).

…native views. All subsequent blocking is handled by separate lock layer, which is of 0.5 opacity. Insertion points / alternative views are locked when parent centre runs / refreshes.
