[PATCH v7 0/1] MR3567: jscript: handle Array.prototype.splice with omitted deleteCount

[Yuxuan Shui (＠yshui)]

Current code handles omitted deleteCount but assumes it to be zero in that case. Instead an omitted deleteCount means delete everything from `start`.

This prevents Adobe sign-in page from loading.
