This happened when linking from a BWS on Believe -- select adelphe/sister in Greek Words | ESV and click on "believing" in 1 Cor 9.5. Using 4.5a SR-1.

The ESV tab is in the layout but was not open prior to linking.
I repeated by navigating to Gen 3 with Interlinear now displayed, clicking on another tab in the pane (to hide ESV) and then selecting the link in BWS. The Interlinear displayed Gen 3 (no change) but became blank when I clicked on "believing" in the ESV!

EDIT: I can reproduce this in 4.5b
