### Steps to reproduce

**Repro steps:**
1. Open the 'windows terminal' application.

### Expected Behavior

The selected state of the controls within the "Find" control should be clearly visible, even in dark mode. Proper contrast and visual indicators should ensure that users can easily identify which options are selected.

### Actual Behavior

In dark mode, the selected state of controls within the "Find" control is not clearly visible. The lack of proper highlighting or contrast makes it difficult to distinguish which controls are selected.

Start by reproducing the issue in Windows Terminal Preview with dark mode enabled, then trace the Find control and its selected-state styling. Done means selected Find controls have clear contrast and visual indicators in dark mode; repeat the listed steps to verify the result.
