also needs to observe contentSize property in order to handle pasting many line and deleting many lines in a single action

[eventomer]

something like this:

    [self.KVOController observe:self keyPath:@"contentSize" options:NSKeyValueObservingOptionNew block:^(id observer, id object, NSDictionary *change) {
        typeof(weakSelf) strongSelf = weakSelf;
        if (strongSelf.isExpandable) {
            [strongSelf handleExpansion];
        }
    }];
