Well, I think I found the answer in the Ace Editor source code.
When using the editor for writing code, this would show syntax errors.
The message is defined here: https://github.com/ajaxorg/ace/blob/9b5b63d1dc7c1b81b58d30c87d14b5905d030ca5/lib/ace/ext/error_marker.js#L122
And the key bindings are set here: https://github.com/ajaxorg/ace/blob/c8b002766964dd0f61c402e3498d6c111fa5afea/lib/ace/commands/default_commands.js#L56-L75
Maybe in a couple of weeks I can try to get Joplin building locally and see if I can configure the editor to exclude that command and/or keybinding. But… I am not a JS dev and if anyone else thinks that is an easy fix in the meantime, it would not be stepping on my toes for someone else to fix this.
