Adding media embed does not move focus out of the toolbar

📝 Provide detailed reproduction steps (if any)

1. Open the examples, classic-editor predefined build in docs
2. Either focus editor's toolbar with keyboard, or select media-embed with mouse
3. Insert media embed.

✔️ Expected result

Media embed is correctly selected, and you can continue to type freely.

❌ Actual result

It looks as if the focus is on both the toolbar and on the added media. You can't type, and when pressing enter it will open the media-embed dropdown again.

📃 Other details

• Browser: Chrome, Firefox, Safari

It works a bit differently on Safari, as trying to add any letter/number once moves the focus back on the added element.
