Version

Please specify what version of the library you are using: [ v3.19.0 & In dev branch as well]

Expected / Desired Behavior / Question

While adding a new term using ModernTaxonomy Picker, the newly added term should be added as a child to its parent.

Observed Behavior

While adding a new term using ModernTaxonomy Picker, the newly added term is adding to the parent level as below.

If the panel is refreshed, the newly added term is properly set unders its parent.

Steps to Reproduce

I was implementing Adding new terms in ModernTaxonomyPicker control for a client as below, using the advanced example as mentioned in the documentation

where updateTaxonomyTreeViewCallback implements to refresh the panel with the newly created term.
The newly created term is created, and shows at the parent level which it should not.

Note

I will be happy to send in the PR for this, as the client needs this functionality.

Thanks!
