Update options from directive

[NavCore]

I have directive which shows tooltip if text is overflowed.
There is a question in the issues can we add v-tooltip directive to DOM element so I will not ask that again,
so I added v-tooltip directive in the template.
But would need to define/change tooltip options in a directive.

Directive has access to DOM element which has _tooltip prop, but changing it's options (for example trigger: 'manual' doesn't affect.
Also directive has access to vnode too.

How to change tooltip options from a directive?
