${\ce {Fe^{2+}+ H2O -> X\\2019-06-06}}$ renders wrongly. It seems to me that X^{2+} is detected as "unusual" and the fallback logic (omitting all spaces) is applied.
${\ce {Fe^2+ + H2O -> X\\2019-06-06}}$ works fine. I double checked, X^{2+} is definitely covered by the strict simplified mhchem grammar.
