Yes, but in this case, animations setting animated properties into
getOverrideStyle (as specified in the SVG spec), it's the UA itself that
does that, and the UA of course also has write-permission into
getComputedStyle

I'm trying to implement it in my LXViewer, and that's why I need to know how
it works. Are you saying that writing into getOverrideStyle (by UA itself or
a user), that also changes the values that are in getComputedStyle?
If that's true, I can see how that works now, For a given element, the UA
computes the computed properties based on stylesheets etc. and then looks at
the override style on the element to see if there are any properties there,
and then "overrides" the computed style with those.

Is that how it works?
