This is not a huge deal, but was unexpected behavior for me. In it's own resource window the FSB can be set to display the "head-word phrase" in a handful of different Bible versions. This is a very nice feature and I simply assumed that if I have the FSB in Multiview with the ESV being the "host," the ESV text would be used in the FSB, but alas, it only displays the default (LEB) text.
