Log Message:
-----------
Fix assertion and enable enhanced security with site isolation enabled
https://bugs.webkit.org/show_bug.cgi?id=323459
rdar://184250733
Reviewed by Sihui Liu.
This assertion was failing in
BrowsingContextGroup::addFrameProcessWithoutInjectingPageContext:
!m_processMap.get(site) || canReplaceFrameProcessInProcessMap(site,
*m_processMap.get(site))
The assertion just needed a slight update to allow replacing processes with
different
enhanced
security states.
All the tests passed already, this just makes them also pass in debug builds
with site isolation.
