Hi Team,,

While going through Blink's commit, I came across another potential patch, which can be discussed to harden Webkit by introducing null check.

Blink Commit - https://chromium.googlesource.com/chromium/blink/+/720d15358dc57c4b7b0a41ef52e2f16888e0a554

Webkit GitHub Source - https://github.com/WebKit/WebKit/blob/d80ae68ecc7a4a5756a38de4a2eb3d2360375012/Source/WTF/wtf/Vector.h#L157 & https://github.com/WebKit/WebKit/blob/d80ae68ecc7a4a5756a38de4a2eb3d2360375012/Source/WTF/wtf/Vector.h#L187

Appreciate if someone can share input whether we need this or not.

Thanks!
