I am not sure this has anything to do with pre-warmed processes. Based on the description, the issue seems to be related to PageCache and how it is implemented with Process-Swap-On-Navigation. When navigating back here, we swap back to the original process and leverage the PageCache entry in that process (this was important to keep PageCache functionality when we implemented process-swapping). The issue in question here seems specific to GTK here so I am not sure I will be able to help much. I am not familiar with webkit_web_extension_initialize / g_message. It seems like the developer wants to know we swapped back to another process and is currently not getting notified when the process is a "suspended" process (i.e. process kept around simply for PageCache purposes). I am happy to answer process-swap related questions if it helps GTK-port developers fix this issue.
