The rebase onto U3 brought in A1's "Available in a project" chooser. Its
change handler kept one renderer and wrote into the first table in the
document, keyed by the page's organization. The rebase resolution keys
the renderer and the choice by each grid's organization and redraws the
table in the chooser's own section. This test covers it: before that
change, pane b's choice never redrew pane b.
