[BUG] IconTabBarTab params aren't async

[KamilaZaeva]

We're trying to re-write old Tab Component with Icon Tab Bar in our project (SAP Minutes).
And use fdp-icon-tab-bar-tab for tab content.
We need to show count of elements for each tab and this count is dynamic.
But unfortunately, both label and counter params looks not async.

Stackblitz example here
I change the name and counter by click - and we can see updated value in the tab content below, but both params in tab hasn't been changed:

I couldn't find any such examples in your documentation or similar open issues in Github.
Feel free contact with me directly via sap account if you need any additional information.
