>+        REGRESSION: Layout test editing/selection/ios/selection-after-changing-text-with-callout-menu.html is failing
>+        https://bugs.webkit.org/show_bug.cgi?id=197532
>+        <rdar://problem/50177144>
>+
>+        Reviewed by Ryosuke Niwa.
>+
>+        Fixes layout tests that began failing after r244546. See below for details.
>+
>+        * UIProcess/RemoteLayerTree/RemoteLayerTreeDrawingAreaProxy.mm:
>+        (WebKit::RemoteLayerTreeDrawingAreaProxy::commitLayerTree):
>+
>+        Partially reverts a change in r244546, after which we commit the layer tree and scroll before updating the
>+        page's editor state. The purpose of this change was to ensure that UI process-side element focus scrolling logic
>+        would not conflict with web-process-driven scrolling logic.
>+
>+        Instead, we split the existing logic in WebPageProxy::editorStateChanged into two pieces: one that updates the
>+        editor state (by setting m_editorState), and a second that dispatches updates to PageClient when the first
>+        editor state is received after focusing an element. During a layer tree commit in the UI process, we first
>+        update the editor state, then commit the layer tree and apply scroll position changes, and finally scroll to
>+        reveal the focused element if necessary.
>+
>+        When an editor state is delivered to the UI process in an out-of-band update (i.e. not in a layer tree commit),
>+        simply dispatch the initial editor state for a focused element immediately.
>+
>+        * UIProcess/WebPageProxy.cpp:
>+        (WebKit::WebPageProxy::scheduleFullEditorStateUpdate):
>+
>+        Add an IPC message to schedule an editor state update in the next remote layer tree commit. See below for more
>+        details.
>+
>+        (WebKit::WebPageProxy::editorStateChanged):
>+        (WebKit::WebPageProxy::dispatchDidReceiveEditorStateAfterFocus):
>+        * UIProcess/WebPageProxy.h:
>+        * UIProcess/gtk/WebPageProxyGtk.cpp:
>+        (WebKit::WebPageProxy::updateEditorState):
>+        (WebKit::WebPageProxy::editorStateChanged): Deleted.
>+        * UIProcess/ios/WKContentViewInteraction.mm:
>+        (-[WKContentView willFinishIgnoringCalloutBarFadeAfterPerformingAction]):
>+
>+        Additionally ensure that an editor state update is scheduled. This addresses a potential source of flakiness in
>+        the layout test editing/selection/ios/selection-after-changing-text-with-callout-menu.html, where an editor
>+        state update may only be scheduled after the next layout timer fires (this is the case in custom callout menu
>+        actions that change the DOM but do not otherwise trigger any editing commands).
>+
>+        In the problematic scenario, the client could make a change that triggers layout soon; but before the layout
>+        timer fires, the timer for the next remote layer tree commit could fire, such that the next layer tree commit
>+        would not contain the relevant editor state.
>+
>+        This extra step ensures that we always *schedule* an editor state update when performing a callout menu action
>+        that does not automatically dismiss, so that we can prevent the callout bar from dismissing during the correct
>+        scope.
>+
>+        * UIProcess/ios/WebPageProxyIOS.mm:
>+        (WebKit::WebPageProxy::layerTreeCommitComplete):
>+        (WebKit::WebPageProxy::updateEditorState):
>+
>+        Rename editorStateChanged to updateEditorState, and make the editorStateChanged codepath only executed when an
>+        out-of-band editor state update is delivered to the UI process.
>+
>+        (WebKit::WebPageProxy::dispatchDidReceiveEditorStateAfterFocus):
>+
>+        Notify the UI process that the initial editor state has been received; this prompts us to scroll to reveal the
>+        focused element, if needed.
