            Bug ID: 217228
           Summary: Multiple calls to suspend media playback for the same
                    WKWebView may result in resuming media playback too
                    soon
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
          Assignee: webkit-unassigned at lists.webkit.org

It’s possible that multiple calls to _suspendAllMediaPlayback() could occur in the same WKWebView with different expectations of when to resume. The current implementation will resume after one call to _resumeAllMediaPlayback(). Instead, we should make sure that all calls to _suspendAllMediaPlayback() have been resolved with _resumeAllMediaPlayback() before actually resuming media content. Adding a counter to track how many calls to suspend have been made and only resuming when the counter is at 0 is a potential solution.
