            Bug ID: 232613
           Summary: [GTK] Run Javascript in a dedicated thread?
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mcrha at redhat.com

Looking into backtraces provided in:
https://gitlab.gnome.org/GNOME/evolution/-/issues/1679#note_1299118

The WebKitWebProcess is busy in the JavaScript call. As it's executed on the main thread the whole process is blocked and any attempt to talk to it (over D-Bus) leads to time outs and the GUI is not updated as well.

Would it make sense to call the JavaScript code in a dedicated thread, thus the call can be eventually cancelled from the main process? I can understand the JavaScript code blocks the GUI repaint.
