Original description:

    Revert "Merge 281715 "[Android WebView] Terminate execution of stuck JS ...""

    This reverts commit 8508a2f18909b0768d273bb9161aee749f47beca.

    As described in the bug, the proposed approach is invalid, as Blink's bindings
    code isn't ready to deal with terminated scripts properly, resulting in random
    crashes. Hence reverting the patch.
