Animation in Top Component title when using 'makeBusy' method

[mimecar]

When we have an operation that lasts over time, we can use the 'makeBusy' method of the Top Component. In Netbeans 8.2, this method put a small animation on the Top Component title.

With Netbeans 21, the method does not work. Analyzing the code, the topComponentMakeBusy() method is called. This method, according to the documentation, does nothing in the default implementation.

https://bits.netbeans.org/20/javadoc/org-openide-windows/org/openide/windows/WindowManager.html#topComponentMakeBusy-org.openide.windows.TopComponent-boolean-

Is it possible to somehow replicate the 'makeBusy' method that worked in Netbeans 8.2?

Thanks for your time.
