Open ESV and Interlinear panel.
Navigate to John 3:16.
In the Interlinear panel, click on successive words to the left of the highlighted word and watch as the Interlinear panel scrolls to adjust itself so the word you just clicked on is highlighted and centered.
As you keep doing this, the Interlinear pane will eventually scroll to a previous verse which is not visible up above in the English text pane.
Expect: the English text to scroll along with the Interlinear pane if necessary.
