Enable Custom Styles on Secondary Windows?

[Eunomiac]

VSC is slowly improving its support for multi-monitor workspaces with better handling of new windows (via File → New Window or CTRL-SHIFT-N), including them in the saved session data so they're restored when reopening your workspace, but

Problem: Custom styles (and scripts) are only added to the DOM of the first/main VSC window. The separate DOM trees of additional windows aren't currently being modified by the extension.

Expected Behavior: Styles and scripts should apply equally to all opened windows of a VSC instance (or a setting should permit enabling this, if making it default behavior risks messing with users' customizations)

Why on Earth would the bot close an open issue simply because no one has commented on it? My initial submission included all necessary information, and Custom Styles still do not apply to secondary windows.
