Because this is a condition that causes the issue, as specified in the commented lines of the patch.

And if You want to add weight on custom fonts (using of course the patch) in Epub You must use ttf fonts, not otf fonts, while with Kepub You can add weight also to otf fonts

Do I need to disable whole section (KePub stylesheet additions) or just change:
# - FindReplaceString: {Find: "/******************************************/", Replace: "body{text-renderingptimizeLegibility }", MustMatchLength: yes}

into:
- FindReplaceString: {Find: "/******************************************/", Replace: "body{text-renderingptimizeLegibility }", MustMatchLength: no}


Thanks for answer
