Created attachment 326702 [details] [Animated GIF] Bug Clicking on a property with index=N should add a blank property at N+1. Instead, it sometimes adds it at N+2.

Created attachment 331359 [details] [Animated GIF] Indices don't get updated I added this CSS for debugging: .spreadsheet-style-declaration-editor .property[data-property-index]::before { content: attr(data-property-index)': '; color: red; } On the attached animated GIF you can see that the indices don't get updated after a blank property is discarded.
