Confused on what is the point of the Tooltip.Portal

[dimitur2204]

I have been looking at creating a new Tooltip for an internal library using Radix. I first took a look at the docs on the Tooltip and noticed that on many of the examples the Tooltip.Portal from the "Anatomy" tab is not present.

In that case what is the point of having it? I also see that shadcn/ui in their implemented primitive also don't use it.

This is all the documentation says:

Portal

When used, portals the content part into the body.

I am struggling to understand what that means.

Ok I see. It just moves the content out to the bottom of the body or whatever element you specify on the portal's container prop. It is not a neccessarry prop to use.
How is that Portal different for Modal, Tooltip, Popover etc. I still do not understand.
