The JFileChooser is also kind of top level component and it has the peer. Current patch does not work as intended. On macOS in Nimbus/Metal L&F the list of files looks disabled but scrolling works. On Aqua L&F the list of files does not look like disabled, accept scroll and double clicks, but does not accept single clicks.
