The isVisibleElement hook is used to dynamically load the grid definitions from the database.

Known limitation: If being logged in in the backend and frontend preview is used with show all elements
it does not work!

@param \Model $model     The row model.
@param bool   $isVisible The current visible state.

@return bool
