With Calibre 5.15, and now 5.16, the "Compress images losslessly" feature of the E-book editor his not working properly. If I use it to do a lossy compression it appears to work, and reports the new, smaller file size in the file browser, but if I save and close the editor, then later re-open the same file, the image will have gone back to it's original (pre lossy compression) size.

I am running Calibre 5.16 on Linux Mint 20.1 “Ulyssa” Cinnamon Edition.
