EVKey does not seem to work with VS Code when the setting editor.experimentalEditContextEnabled is true

Hi. I am a developer on the VS Code core team. I am writing here in relation to a bug I have received recently here microsoft/vscode#239559. It would seem that when our setting editor.experimentalEditContextEnabled is true, we no longer receive correct composition events when users type using the EVKey input method. This does not seem to happen with the Vietnames Telex input method, so it seems to be specific to EVKey. I am not sure what is causing this, but I wanted to let you know, in case this is maybe an issue with EVKey.
