Okay, but that's not a documented use-case, so I'm not sure that it's a
bug.  The thing you suggest may be possible, but would require
developing a new feature, for example to run two instances of the same
spell checker at once.

AFAIU, the best solution is to use an external spell checker that has
support for using two languages at once.  Why not use that?

Best regards,
