* feat: add support for node / preloads in subframes This feature has delibrately been built / implemented in such a way that it has minimum impact on existing apps / code-paths. Without enabling the new "nodeSupportInSubFrames" option basically none of this new code will be hit. The things that I believe need extra scrutiny are: * Introduction of `event.reply` for IPC events and usage of `event.reply` instead of `event.sender.send()` * Usage of `node::FreeEnvironment(env)` when the new option is enabled in order to avoid memory leaks. I have tested this quite a bit and haven't managed to cause a crash but it is still feature flagged behind the "nodeSupportInSubFrames" flag to avoid potential impact. Closes #10569 Closes #10401 Closes #11868 Closes #12505 Closes #14035 * feat: add support preloads in subframes for sandboxed renderers * spec: add tests for new nodeSupportInSubFrames option * spec: fix specs for .reply and ._replyInternal for internal messages * chore: revert change to use flag instead of environment set size * chore: clean up subframe impl * chore: apply suggestions from code review Co-Authored-By: MarshallOfSound <samuel.r.attard@gmail.com> * chore: clean up reply usage * chore: fix TS docs generation * chore: cleanup after rebase * chore: rename wrap to add in event fns
