Spell check language does not change when changing keyboard language

Which version of the software are you running?

Fairphone OS 22.02.0-rel.0 (but previous A10 versions also exhibited this)

What happened?

I frequently switch my keyboard language between Dutch, English and German (QWERTY) using the 'globe' button on the default keyboard. This works fine as far as the keyboard layouts and auto-correct are concerned, but the system spell checker stays in Dutch regardless of the language in use, so texts in other languages show many red lines under the words while typing.

Expected behavior

The spell check occurs in the currently selected keyboard language, at least as soon as you start typing in the new language.

Steps to reproduce

• Configure a second keyboard language in Settings > System > Languages and input > Virtual keyboard > Android keyboard > Languages.
• Open any app which allows typing with spell-checking (e.g. Signal, Telegram or WhatsApp.)
