            Bug ID: 202860
           Summary: [WebVTT] Embedded Style Interoperability Issues
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: evliu at google.com

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_*
