Problem description

After the focus has moved to the ref panel, navigating the focus back to the blob view is quite time-consuming (hold Shift + Tab for long or lots of key presses). This makes using the ref panel tedious.

(This point applies to keyboard navigation too.)

Expected behavior

I think we should modify the tab hierarchy or the page structure so that one can quickly navigate back from the ref panel to the blob view, perhaps to the specific part where the code intel popover was triggered.
