👋🏻 @geriux I think I may still be encountering this issue with the Geologist theme with Jetpack iOS 23.9.0.1. Would you be willing to see if this issue occurs for you as well?

1. Disable dark mode.
2. Enable the Geologist theme.
3. Launch the editor.
4. ⚠️ An unexpected, illegible black text is rendered atop a dark theme background color for the editor canvas.
