[css-scroll-anchoring-1] Should changes to 'overflow-anchor' invalidate the scroll anchor?

[eqrion]

#3476 adds some more details for when scroll anchors should be invalidated.

Should changes to the 'overflow-anchor' property invalidate the current scroll anchor?

I think that makes sense, as a change to 'overflow-anchor' can change the effective anchor node. However, we don't invalidate after every property that could change the effective anchor node, such as 'border' (#3321).

I guess maybe changing 'overflow-anchor' has a high intention that you want to change the effective anchor node?

I don't think this is controversial at all, let's just make the change. PR in review.
