Custom block categories don't show up in the card view

[fabiankaegy]

I have registered a custom Block category via PHP and am using the name of that custom category in the registerBlockType function. But it doesn't show up in the Card view.

I guess the block registration ensures that the category exists on the frontend otherwise it reset it to "undefined". I think you should call wp.data.setCategories on your .blockbook/index.js file with your custom categories in addition to the Core categories.
