Android Chrome issue with menubuttons

📝 Provide detailed reproduction steps (if any)

The issue can be reproduced using Chrome on Android by:

1. Visiting the inline editor example
2. Click on the body text below the image. [Edit: Ensure the Android on-screen keyboard is showing]
3. Click on the font selection menubutton

✔️ Expected result

The menubutton menu should open

❌ Actual result

The entire toolbar disappears, as if the editor lost focus. This makes it impossible to use the menubutton.

Note: A similar behavior happens in the non-inline editor; the issue is just more obvious and problematic in the inline editor. In the basic editor, when the focus is inside the editor text, when a menubutton is clicked the first time the editor loses focus and the menu doesn't open. A second click will open the menu.

📃 Other details

• Browser: Chrome 138.0.7204.179
• OS: Android 16 on Pixel 9a
• First affected version: Based on trying the examples for previous version, this issue first appeared in version 7
• Worked in version: It seems to work fine in version 6

If you'd like to see this fixed sooner, add a 👍 reaction to this post.

Start by reproducing the issue in the inline editor example on Chrome for Android with the on-screen keyboard visible, then compare the basic editor behavior. Trace the menubutton focus handling and compare the working version 6 behavior with version 7 and later. Done means the menu opens on the first click and the toolbar remains visible in both inline and non-inline editors.
