Set tooltip collision boundary to e.g. drawer or modal, not whole viewport

[paprikati]

I suspect this is supported and I'm just failing to read the docs correctly.

We often render tooltips within components like drawers or modals.

In these situations, we want the tooltip positioning logic to treat the drawer as its 'viewport' - i.e. avoiding collisions, just like it would with the whole screen if this element was positioned on the right.

I can see that you can pass in a collisionBoundary element, but don't really understand how that works given the drawer is a parent of the tooltip

Suspect I am being dim - would love some help from someone who understands these primitives better than I do!
