This issue is not limited to WebExtension APIs:

`composeWindow.SetComposeDetails({ body: "Something" })`

uses `editor.document.dDocumentElement.innerHtml =` [1] to update the
content of the editor. The `error` event hanlder used for handling
of blocked images is currently attached to `editor.document.body` [2].
After the editor content has been replaced as described, this event
listener no longer exists, and blocked images are therefore not handled
anymore.
