[Interest] Double free in QItemDelegate editor
Hello, My project (CMake GUI) has a class which extends QItemDelegate and overrides QItemDelegate::createEditor(). However, the editor that gets returned by this method gets double-freed, and I'm not sure exactly why. (I did notice that QItemDelegate::destroyEditor() calls the editor's QObject::deleteLater() by default - does the editor already get deleted when its parent gets deleted?) What's interesting is that this issue only happens when using the Qt binaries from https://qt.io/download. When I use the system binaries from APT (which I believe ultimately delegate to GTK), everything works fine. Any ideas on what might be wrong?

Re: [Interest] QtWebkit stylesheet issue using css
Does it makes sense to QtWebkit 5.6.3 incase this issue had been introduced in latest WebKit 5.212 or move to Qt webengine though there is no direct API for setuserstylesheet? Let me know your feedback in this regard.
