Wrong dark theme styling of 3rd level properties and dropdown

[protyposis]

I am observing styling issues in v2.1.2 (with Docusaurus 3.5.2):

• 3rd level background has unexpected light border
• dropdown background and text are both lightly colored and text is barely readable

I have tried various Infima CSS variables, Docusaurus and Redoc styling config properties, but wasn't able to modify these colors. Since this was reported as a similar bug in the past at #13, I am wondering whether this is a regression and if there is a way or workaround to fix it?

Here's a screenshot and a minimal OpenAPI example spec:

Thank you!
