ipcRenderer.postMessage should throw error when contextIsolated is enabled

Describe the bug

It wasted me hours figuring out why ipcRenderer.postMessage has no effect at all. 😂
Then I read the source code and found out if contextIsolated is enabled, the function just returns silently, which I believe is a bad practice.
