This issue is a combination of Caja and trash applet from what I see, not necessarily only issue with trash applet. On MATE (Caja) in other distros like Debian, even LinuxMint, we get a dialog to empty trash from external drive to save space on that drive. If we agree trash is emptied and trash icon reflects status correctly. If we eject without emptying trash, the trash-icon stays full. However, on Ubuntu MATE there is no pop-up dialog unlike in other distros when there is deleted content; it just ejects the medium. UM is deviating from default behavior.
