Please add a test case.

I don't think the error is fixed. The current category is still saved in state and is not updated on ui schema changes.

Hi @TheZoker , thanks for the contribution.
I left some comments inline. Please have a look :) The two main issues atm seem to be:

• In CategorizationList, and endless loop is created by handing down the same filteredCategories. This causes the out of memory error during tests. More details are in the comment inline
• The new filteredCategories prop is of the wrong type and does not consider Categorization elements despite them effectively being handed down. Handing them down seems to be correct because otherwise we could no longer handle nested Categorizations. The type and potentially the prop name should be fixed accordingly.

Thanks for the updates. Looks better now :) I have two remarks inline.
Furthermore, the vanilla example app and some tests for the input control and the categorization renderer are failing.
I have a suspicion regarding the example app and input control: packages/vanilla-renderers/src/util/renderer.ts being in the util folder creates a circular dependency. Thus, renderer.ts should be moved up one folder to be directly contained in the src folder.
Please also have a look at the categorization renderer tests.

Looks good! Can you squash this into 1-2 nicely formatted commits?
