Keyboard layout indicator on panel is incorrect; if panel bar invoked to show up by shortcut key

If panel bar is set to be automatic hidden and then getting triggered/invoked to show up by (only by, likely) shortcut key for invoking Whisker menu, then the keyboard layout indicator printed/shown on panel is incorrect if it's being as not primary/main keyboard layout; it'll be always the primary keyboard layout.

Such is only by (likely) way of shortcut key for invoking Whisker menu, not by hovering mouse to bottom screen

Help fix Thanks before
