I think the worst design is when it's a control-click that will open a new tab, but the SPA trips itself up and goes back to the homepage/index nothing is more painful when, after scrolling through an control-clicking some things that might be what you're looking for, seeing 5 or more tabs open, and then realising that they're all just the default homepage.
