Bug ID: 56649
Summary: VisualEditor: Exception when undoing foreign image
insertion
Product: VisualEditor
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: ContentEditable

1. Insert an image from Commons
2. Press Ctrl+Z quickly
When you undo the image insertion, there's still an API request pending. When
it comes back, ve.ce.GeneratedContentNode.prototype.doneGenerating crashes
because the node is now detached.
GCNode should protect against being detached, and should abort any pending
requests when it's detached (the latter alone is not enough: GCNode promises
aren't guaranteed to be abortable).
