Spellcheck missing from Context Menu

Description
For a while context menu displayed the spellcheck option and it was possible to switch between languages.

Is there a way to return this feature? Is it due to Edge updates? If that is the case, is there a way to force WebView2 control to use a specific version of Edge where this was available without actually forcing everyone using the app to downgrade their Edge in order to have this option available?

I have fiddled around with Edge and Windows settings and made sure all spellchecking options were ticked. However, no spellcheck is activated while using the WebView2.

Version
SDK: 1.0.1418.22
Framework: WinForms
OS: Win10

Repro Steps
Right click the document.

The red mark is where spellcheck option was showing (above the writing direction option which is called "Smer pisanja").
Language displayed is Serbian so dont be confused. This was set in the enviroment options in hopes that spellcheck might start working in the desired language.

Additional context

Start by reproducing the issue by right-clicking a document in the WebView2 control with SDK 1.0.1418.22 on Win10, then investigate whether the missing spellcheck menu is controlled by WebView2 or the installed Edge version. Done means establishing whether the feature can be restored or configured without requiring users to downgrade Edge.
