sanketj has just labeled a pull request from dandclark for https://github.com/w3c/csswg-drafts as "css-highlight-api-1": == [css-highlight-api-1] Don't paint highlights that cross contain boundaries == If a StaticRange crosses a `contain` boundary and the boundary point inside the contained element is removed, UAs would have to stop painting the full extent of the range. This would violate the `contain` invariant, since a change inside the element with `contain` would have affected the appearance of content outside of that element. To eliminate this problem, never paint ranges that cross `contain` boundaries. A slightly more scoped solution would be to apply this limitation only for highlights specified with `StaticRange`, but since there doesn't seem to be any use case for applying highlights across `contain` boundaries, the limitation is applied to live `Range`s as well for consistency's sake. This PR changes the range-painting criteria into an algorithm, since precisely expressing the concept of "crossing a contain boundary" is clumsy in prose. Resolves #4598.
