Empty trash disabled

After dropping a file in the trash, I tried to empty it, but the "empty trash" option is disabled in Thunar version 4.16.6. It is necessary to make a refresh in the trash or F5 key to enable this option. Simple reproduction of the bug: create an empty file on the desktop and then, drop it in the trash (delete). I tested Thunar in version 4.16.3, and the bug does not exist in that version.
