Notification opened-changed event spam while using modal dialog

[knoobie]

Description of the bug

When I have a notification and a modal dialog my log is bombarded with log messages.. making me wonder.. is my application broken?

Log from a single button click.

Expected behavior

No log message is provided. Notification works even with a modal dialog - automatical exclusion for server side modal feature?

Minimal reproducible example

    var btn = new Button("Click Me", e -> {
      Notification.show("Hi. I'm a notification.");

      var dialog = new Dialog();
      dialog.setModal(true);
      dialog.add(new Paragraph("Lorem Ipsum. Let this stay open until Notification disappears."));
      dialog.open();
    });

Versions

• Vaadin / Flow version: latest
• Java version: latest

This might need some change in Flow so that we could also use @AllowInert with @Synchronize

[knoobie]

I think I said that something else as well: Synchronize needs an attribute allowInert which is set to true for all Vaadin internal communications to synchronize server and client - this problem is also within the Sidebar and its pretty annoying.

Based on @caalador comment transferring it to the flow repository. We can evaluate if changes are needed on our side once it's addressed.
