Description

I uploaded a few images to a simple site by dragging and dropping them from my computer and it worked, but I got this message:

Editing this Gallery in the WordPress mobile app requires version 18.2 or higher.

it does not make any sense since:

• I am not using the APP
• The upload worked just fine.

Step-by-step reproduction instructions

1. Create a new post (or edit an existing one)
2. Drag multiple images from your computer into the editor
3. Images will be uploaded, but an error message will be displayed at the bottom.

Screenshots, screen recording, code snippet

Environment info

• Gutenberg: v11.9.1
• The issue does NOT happen with the core version of the editor (WordPress 5.8.2)
• This was spotted on a WordPress.com site but I was able to reproduce it on a self-hosted site
• MacOS 11.1 & Google Chrome 95.0.4638.69
