While fixing #13302 we found an issue that can cause an SSR crash if the user has control over an attribute name.
While this situation is likely very uncommon, we've included a fix for this crash in
react-dom@16.4.2
that went out today.We did not backport this fix to other minor releases because it's only a crash.
