Brian Grinstead a8eabad78e Bug 1501845 - Load customElements.js inside migration.xul to fix migration UI when running with commandline;r=paolo ... This is another case of a document getting loaded before MainProcessSingleton, similar to profile manager. There's another wrinkle here, though. The migration UI can also be loaded _after_ startup (through Bookmarks manager), which is actually the primary way this UI is surfaced. So we need to also handle customElements.js getting loaded twice into the same window to avoid attempting to redefine everything.
