"Play" button can still be pressed while disabled

When the play button is disabled, it can still be focused onto and pressed. I believe this wasn't the case a month ago.

1. Launch Minecraft

2. Wait for it to get to the "preparing" stage (the play button shows three dots)

3. Click on the play button
   → ❌ It shows the style of being active, then focused

4. Tab to the play button
   → ❌ It shows the style of being focused
