I am trying to change TextContainer size via [__viewTextContainer
setContainerSize:__sizeToSet]; And this is called in response to
NSTextStorageDidProcessEditingNotification.
The reason I need to change container size, is to update it to keep
all entered text. All the time I am keeping text container as small as
it is possible.
