Electron application with capitalised executable name

Skrifa (source) is an electron snap which currently has a broken .desktop launcher. It is broken because the desktop launcher uses the capitalised name of the executable while the app name is lowercase. As a result, snapd simply filters out the Exec= line of the desktop launcher on install.

Since this snap is generated by electron-builder, I have no idea how to proceed to fix this. Is this a bug in electron-builder?
