The problem is sandboxing an app like Sigil that uses PageEdit as an external editor, that uses OpenWith to open lots of third party editing tools chosen by the user including gimp, svg editors, etc, etc, and third party python plugins that can run lots of OS commands and tools (including java) just makes no sense at all. The flatpak version is quite handicapped and limited.
The right way to effectively "sandbox" an app like Sigil is to run it in a VM with a full set of other tools that can be employed with Sigil (like PageEdit, gimp java, etc etc) to make a VM playground tool).
Have you thought about running a Manjaro VM (or some other linux VM that properly updates things like Sigil) on your linux box and not running flatpak?
