Time Warp spoofing when not connected to proxy

[brogers5]

Description

Time Warp, as described on both the website and within the extension's Privacy menu, mentions that the spoofed time should match that of the location the user is currently connected to:

However, I'm seeing that this feature is always active against the last selected location, regardless of whether I am actively connected to it.

Steps to Reproduce

1. Enable Time Warp.

2. If the current selected Location's time zone matches your current time zone, change to another Location assigned to another time zone.

3. Disconnect from the Location, if needed.

4. Browse to something that detects the user's current time zone.

   In my case, I'm seeing this with the Outlook web app's Calendar:

   

Expected behavior

Time Warp's functionality should not be active when not connected to any proxy location.

Actual behavior

Time Warp's functionality is always active when enabled, regardless of whether the user is actively connected to a proxy location.

Same thing with Split Personality, which changes the user agent even when the connection is disconnected.
