Previously (<1.19.3), the creative inventory remembered the last viewed tab and opened to it by default for the rest of the session. In 1.19.3 this no longer happens, instead it always opens at the "Building Blocks" tab, even if another one was previously selected.

How to reproduce
1. Open a creative mode session
2. Open the inventory
3. Switch to any tab other than Building Blocks (ex. Search)
4. Close the inventory
5. Open the inventory again
6. Notice how it opened to Building Blocks
