tmux.GlobalWindowScope.SetPopupBorderLines(ctx: context.Context, value: PopupBorderLines) -> error
```

SetPopupBorderLines stores the "popup-border-lines" window option as PopupBorderLines (tmux 3.3 or later). Read it with [WindowOptionValues.PopupBorderLines] from [GlobalWindowScope.Options]; [GlobalWindowScope.UnsetOption] restores inheritance or the global default.
