There are several aspects of the WebKit implementation of inline WebVTT styles that do not conform to the spec: https://w3c.github.io/webvtt
Some issues include the following:
- CSS from one track applies to the entire shadow tree scope, including tracks sourced from a different VTT file.
- @import rules are allowed.
- The cascade order of the styles is incorrect.
Test coverage exposing these inconsistencies was added to the Web Platform Tests under the path: webvtt/rendering/cues-with-video/processing-model/embedded_style_*
