Tooltip content is not hoverable

### Feature Proposal

We're using chart JS and accessibility testing team has raised a defect that the Tooltip content itself is not hoverable / selectable which makes it fail WCAG Success criteria

I've created a quick example here:

Having this feature would improve the accessibility of the overall library.

Your kind consideration to add this feature would be much appreciated.
