I recently noticed that Calibre has started adding ~50kb to epubs when I send them to my Kobo Glo. I mainly use my reader to read fanfiction that I download as epubs from Archive of Our Own, the majority of them are <20kb and I download fairly large quantities of them, so this is suddenly eating up my space on the Kobo faster than I'd prefer.
I've been working my way back through the Calibre updates, and with the 2.58 release from June 17 a 10kb epub is still 10kb when it appears on the Kobo, but with the 2.59 release the same 10kb epub is now 63kb on the Kobo.
But that's where I'm stuck. I've spent the last couple of days trying to search the internet and reading the threads here, but I just don't understand enough to figure out what's going on. I'm assuming it's related to something in this part about epubs in the changelog from the 2.59 release? (or is something else going on?):
I'd be so very grateful if anyone had suggestions for how I could disable whatever's going on, or something? My current plan is to just use the 2.58 release indefinitely, but I'd rather find a solution if it's possible. Thanks!

Edit Book: Add support for EPUB 3 to the Table of Contents tool. Now when editing EPUB 3 files using the tool will automatically generate both the EPUB 3 navigation document and the NCX table of contents for backwards compatibility.
EPUB Input: Implement reading of Table of Contents from EPUB 3 files that do not specify a fallback NCX ToC
EPUB metadata: When setting a cover image for an EPUB file that has no metadata cover image defined, add the new cover image as a pure metadata cover instead of aborting.
