Hi Team,

While going through Blink's commit, I found another potential merge, which can make Webkit more stable and not hit situation leading to crash on debug or release builds:

Blink Commit - https://src.chromium.org/viewvc/blink?view=revision&revision=190121

Webkit GitHub Source - https://github.com/WebKit/WebKit/blob/7e26ee98dc891f869c003c1724f061a82d65bd2b/Source/WebCore/editing/DeleteSelectionCommand.cpp#L984

This is to avoid any crash and harden the function.

Thanks!
