            Bug ID: 202568
           Summary: [GTK] Navigation gesture snapshot times out after PSON
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: alexm at gnome.org

A simple way to reproduce: run minibrowser, enable the gesture, go to webkit.com, swipe back. Go to docs or release announcements, swipe back, it works immediately.

The event it's waiting for is RenderTreeSizeThreshold. Looks like ViewGestureGeometryCollector::SetRenderTreeSizeNotificationThreshold() is sent too early, and arrives to the wrong process in case of PSON. And it looks like the same thing should happen on Mac.

Adding a requestRenderTreeSizeNotificationIfNeeded() call in ViewGestureController::connectToProcess() fixes it here, but that's probably not the right solution.
