### Expected Behavior

Screen Reader should announce 'New Tab 48 of 107 Selected Activate for more options' for 'New Tab' list item.

### Actual Behavior

Screen Reader is not announcing any info about '>'(more options) for 'New Tab' list item. Issue repro with all list item control where '>' (more options) control is present.
i.e. For 'New tab.. >' Screen reader is only announcing 'New Tab 48 of 107 Selected'

**Observation:** Issue repro with NVDA and JAWS Screen Reader.

Start by reproducing the issue through Windows Terminal's Command Palette, focusing on the New Tab list item and its more-options control with Narrator, NVDA, or JAWS. Inspect the accessibility information exposed for that control and compare it with the expected announcement. Done means screen readers announce the more-options action for New Tab and the other affected list items.
