Reproduction steps

1. Update buffer_font_family with a font that supports features
2. Update ui_font_features to enable a distinctive feature present in the buffer_font_family
   In my specific case, I'm trialing MD IO, where the ss02 feature, when enabled, will render numbers inside a circle, so I enabled ss02 in the ui_font_family
3. Open any file tracked by git, where the inline blame element is rendered
4. Confirm that the text in the inline blame, even though it's using the font family defined in buffer_font_family, is using the ui_font_features

Current vs. Expected behavior

Current Behavior

The font features defined in the ui_font_features are being applied to the buffer_font in certain editor elements, for example, in the inline git blame ▼

Expected Behavior

When the buffer_font is in use, only the buffer_font_features should be applied.
