Issue with ContextualBalloon Not Appearing After Updating to CKEditor 43.0.0

📝 Provide detailed reproduction steps (if any)

After updating the CKEditor version to 43.0.0, an issue has occurred.

Previously, we were using a custom plugin that utilizes the ContextualBalloon. When clicking the button of the plugin, the ContextualBalloon would appear, allowing text input in the input field.

However, after the update, the ContextualBalloon does not appear when using the custom plugin with the SlashCommand.

What should we do to resolve this?

Thanks for report! I'll take a look. It looks like something is trying to pin itself on the hidden element.
