public void onViewFocusChanged(boolean gainFocus) {
        if (mHasViewFocus != null && mHasViewFocus == gainFocus) return;
        mHasViewFocus = gainFocus;
        onFocusChanged();

        // Stylus Writing
        if (mWebContents.getStylusWritingHandler() != null) {
            mWebContents.getStylusWritingHandler().onFocusChanged(gainFocus);
        }
    }

check classfile and find ''"mHasViewFocus != null" is removed. But dex is normal. Then binary-search r8 commit and find the root cause is this commit:https://r8.googlesource.com/r8/+/aea63008fa7dadc860155c5149ffd00662fe9377. The difference between classfile and dex may be desugering.
