Currently, the FitToViewportLockAction is neither unlocked automatically, nor does it enforce that the contents remain fit to the viewport in all cases. Specifically, the action does only perform fit-to-viewport, when the viewport size is changed. Therefore, the action should get unlocked when the zoom level or the scroll offset is changed.

I added listeners on the various viewport properties (width, height, content-transform, content-bounds, horizontal-offset, vertical-offset) to ensure fit-to-viewport is performed when the size or bounds are changed while locked, as well as to ensure fit-to-viewport is unlocked when the user manually performs scrolling or zooming. The code is published on the master branch, therefore, I resolve this ticket as fixed for 5.0.0 M6.
