When will the sidebar become stable?

I open the sidebar, search for something, and then minimize it. When I focus back on the page and return to the sidebar again, my last query is gone and a new page screen appears. I want to continue from where I left off, just like in Opera. This also causes issues in other applications. For example, when we add WhatsApp to the sidebar and open it, we have to wait for WhatsApp to reload every single time. Without these features, there is no point in using the sidebar.
