Bitwarden extension for Safari doesn't recognize system theme changes between light and dark modes (macOS)

[vobrechkov]

Steps To Reproduce

1. Launch Safari with Bitwarden extension installed
2. If in light mode, change your system to dark mode (or vice versa)
3. Notice Bitwarden extension UI color theme does not change
4. Fully exit Safari (Cmd+Q)
5. Launch Safari
6. Notice Bitwarden extension now uses correct color theme consistent with macOS theme

Expected Result

I expect the Bitwarden Safari extension to respect system theme changes and adjust it's own colors accordingly.

Actual Result

Bitwarden Extension's UI theme does not change after system theme changes
