missing tabs on re-open of Chrome

Like many people have in other issues, I want to start by saying that the work you are doing here and the extension you've made are so important. Finding SideWise has filled a major need and you clearly understand how actual developers, researchers, and like-minded folks browse in the modern era.

My question: I've had to close and open Chrome a few times lately, due to various OS problems. When I've done that, the tabs listed in each window are not the same as when I closed the browser. Why do my tabs go missing after close / re-open?

I donated. If you are reading this and didn't; do.
