Added buffer to all sides of Tooltip's floating content

[smmr-dn]

Changes

This PR added a buffer of 4px to all sides of the Tooltip's floating content so that when users slightly move their mouse outside of the content box, the tooltip is still visible.

Testing

Confirmed that the tooltip is still visible when the mouse moves outside of the border.

There are two things I would like to ask for more opinions in this PR:

• I have tested with and without the safePolygon specified in the useHover hook's option and noticed that even with a larger inset that overlaps the trigger element (I have set the pseudo-element's background to white for debugging), the tooltip disappears as soon as the mouse moves out of it. Should I keep this setup so that the transition between the element and the floating content can be kept?

• I notice the overflow: hidden clips off the edges of the ::before pseudo-element, which results in the buffer size not showing up correctly. Can we either set overflow to either unset or visible for this buffer content to be fully shown?

If it doesn't behave properly without safePolygon, then yeah we should keep it.

Yeah that's fine. I'm not sure why we even had overflow: hidden (looks like it was added 3 years ago without any explanation).

LGTM and nice work! Just make sure to add a changeset.
