"Edit Metadata" window grows taller with each export

[Glenn]

When exporting in formats with metadata (eg FLAC), the additional dialog after the export dialog, "Edit Metadata", gets taller with each file you export, until it's the full height of the screen.

To reproduce: Create any small audio file, and export it to FLAC. Keep exporting it, and the dialog gets taller with each export.

Expected: Well, the dialog box should stay the same size!
