Either you added the "liga" feature to U+2116 or the version of
FontForge you used did.
It seems older versions of Fontforge added liga features where some
characters can be decomposed or, in your case, where approximate
equivalents exist. This has been changed in more recent versions of
FontForge but your file still has those unwanted ligatures.
