            Bug ID: 280824
           Summary: [iOS] Snapshot using`takeSnapshotWithConfiguration`
                    misses HTML video
           Product: WebKit
           Version: WebKit Local Build
          Hardware: iPhone / iPad
                OS: iOS 17
            Status: NEW
          Severity: Major
          Priority: P2
         Component: WebKit API
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: radunitescu at google.com

Taking a snapshot using `takeSnapshotWithConfiguration:completionHandler:` of a webpage containing a html video does not include the video portion - it is replaced by a black rectangle.

Steps to reproduce:
Take a snapshot of `WKWebView` on iOS 17.5 or 18.0 (iPhone XR) with `takeSnapshotWithConfiguration:completionHandler:` of a webpage that is playing an HTML video (e.g. https://www.youtube.com/watch?v=eDqfg_LexCQ)

Expected behavior:
The snapshot is taken and includes a frame of the video.

Current behavior:
The snapshot is taken but does not include the video portion (being replaced by a black rectangle). The rest of the content is correctly captured in the image.
