### Issue Tracking Info

- [x] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

Start by reproducing the Windows Hello unlock flow in the Firefox browser extension on Windows 24H2, then review closed PR #16187 for prior investigation. The work is done when the Windows Hello dialogue reliably opens in the foreground instead of requiring taskbar interaction.
