IntelliJ plugin: Navigate from Project View to a file without triggering AutoScrollFromSource?

I'm writing an IntelliJ IDEA plugin and I am trying to navigate from the project pane to a file without triggering "autoscrollfromsource" function (even if it is turned on).

I tried temporarily disabling autoscrollfromsource (and re-enabling it afterwards) but this attempt was not successful.

In the code below, it seems it takes a moment for the file to load, and by that time autoscrollfromsource is already re-enabled.

private void navigateWithoutAutoscrollFromSource(final ProjectViewImpl projectView, BasePsiNode<? extends PsiElement> node) {
    boolean wasAutoScrollFromSource = projectView.isAutoscrollFromSource(PROJECT_PANE);
    if (wasAutoScrollFromSource) {
        projectView.setAutoscrollFromSource(false, PROJECT_PANE);
    }

    // this navigation here should NOT trigger autoscrollfromsource!!
    node.navigate(true);

    if (wasAutoScrollFromSource) {
        ApplicationManager.getApplication().invokeLater(new Runnable() {
            @Override
            public void run() {
                projectView.setAutoscrollFromSource(true, PROJECT_PANE);
            }
        });
    }
}

Is there a better way to navigate to my node, without triggering autoscrollfromsource?

Thanks for any pro tips :)

Update 1

I trace the code to the openapi class OpenFileDescriptor, here:

public void navigate(boolean requestFocus) {
    if (!canNavigate()) {
        throw new IllegalStateException("Navigation is not possible with null project");
    }

    if (!myFile.isDirectory() && navigateInEditor(myProject, requestFocus)) return;

    navigateInProjectView();
}

Basically, I would like to be able to execute this navigate method, without it triggering autoscroll from source.

If navigate(false) isn't enough. You can listen for FileEditorManager events, and stop the editor you open from becoming the selected editor.
