Function getScrollParent in swagger-ui/src/core/plugins/deep-linking/layout.js derivative work of stackoverflow code under CC-BY-SA 3.0?

Hi,

While performing some review of swagger-ui, I ran into the following code snippet at
https://github.com/swagger-api/swagger-ui/blame/master/src/core/plugins/deep-linking/layout.js#L138:
Function getScrollParent apparently is derivative work from code published on stackoverflow in 2017, as attributed in the accompanying comment (pointing to https://stackoverflow.com/a/42543908/3933724).
However, this code from stackoverflow was presumably published under a CC-BY-SA 3.0 license by default
(see https://stackoverflow.com/help/licensing).
Here it is re-licensed under the Apache-2.0 license, which AFAIK is not compatible with CC-BY-SA 3.0.
Isn't there a license issue here with the inclusion of this code snippet?

Best regards,
Alain Le Guennec
