Unfortunately, this is not a bug in Konqueror itself, but by QtWebEngine, the web engine used by Konqueror and provided by Qt. Other browsers using QtWebEngine, such as Falkon, QuteBrowser and the example browser included in QtWebEngine itself. I created a bug report for this issue in the Qt bugtracker (https://bugreports.qt.io/browse/QTBUG-126701) and I'll close this one as an upstream issue.
