No option to save as webpage complete google chrome

[erie88]

So my google chrome didn't have the option to save page as webpage complete. Searching on google, this problem has already been solved according in https://bugs.kde.org/show_bug.cgi?id=295820#c6. But it only link to a kde-baseapps repository revision https://projects.kde.org/projects/kde/kde-baseapps/repository/revisions/36733fdcc1242a15374672b6e39e906bb131b958. I have already downloaded the tarball version of kde-baseapps. I don't know what to do after this.

Anyone could help? Or maybe let me know the exact location of kdialog.cpp, is it in home or root folder? Thanks.
