Much better.  Still _not_ an admission that it is an implementation bug 
caused by the original JavaScript code as Dr. Rauschmeyer and you claimed, 
and not a clear admission that it is a bug at all (“reason to believe”,
not “is”).  But at least properly quoted and cited, and substantiated.

Evidence is not proven, but presented.  “Evidence” is synonymous with 
“proof; so “to prove evidence” contains redundancy, at best.

You should improve your understanding of English; that way the number of 
your misconceptions – about what people said and wrote, and what they meant 
when they said and wrote it – might decrease.
