Custom Property Drawers fail to inherit properly when their Assembly's name has a space in it

How to reproduce:
1. Open the attached Project "drawerTest" and load Scene "SampleScene"
2. In the Hierarchy, select the "GameObject" GameObject
3. In the Inspector, under the "Test" Component, swap between the values of "Type"
4. Observe the Color field on the Component

Expected result: the Color is Green for "None" and Red for "Custom"
Actual result: the Color is always Green

Reproducible with: 2021.3.20f1, 2022.2.10f1, 2023.1.0b6, 2023.2.0a4
Could not test with: 2020.3.46f1 (Errors in scripts)

Notes:

• Removing the space from the Assembly Definition Asset's "Name" field makes the Color swap correctly
