Prevent collapsing every tab group when collapsing sidebar

I'm not sure if this is even the right place to ask this, or voice this complaint if there's no fix. If not, please direct me where to go.

I'm trying to switch all my development over to Safari, but the tab sidebar is driving me absolutely insane.

Let's say I have a bunch of tab groups expanded, and I collapse the sidebar to focus on the webapp I am building. When I toggle to show the sidebar again, every single tab group is collapsed.

Why is it 2 clicks to see the tabs in the sidebar?

Even with zero tab groups, and just tabs in the workspace, if you collapse the sidebar it'll collapse the list of tabs.

Is there some hidden setting for this? Who do we have to complain to?
