Closes #7306 We started noticing that when a `TextEditor` pane got split, the same view for `Gutter` was being shared amongst several models, thereby making the same DOM element accessible simultaneously by more than one object. This made us experience *orphaned line numbers*, caused by two instances of `LineNumberGutterComponent` mutating `.line-numbers` at the same time. This is a typical race condition which I would normally address by understanding and possibly locking the correct order in which operations should happen. However, I believe in this situation we shouldn’t actually care about ordering at all, since I think views should be kept “local”, thus avoiding to expose them to the world and/or reusing them across other views (either accidentally as in this case or on purpose).
Atom is a hackable text editor for the 21st century, built on Electron, and based on everything we love about our favorite editors. We designed it to be deeply customizable, but still approachable using the default configuration.
