Ability to disable a tooltip

[rowanwins]

• I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

Sometimes you may want to disable a tooltip if a certain condition is met - however you always want the inner content.

What does the proposed API look like?

<a-tooltip :disable="condition" title="Condition was met therefore...">
    <p>Text that I always want visible</p>
</a-tooltip>
