Problem Description

I moved from BrowserWindow to a BaseWindow with one or more webContents (via WebContentsView). I'd like to know when each of the webContents are ready-to-show.

Proposed Solution

I propose this API:

webContents.on("ready-to-show", () => console.log("ready-to-show"));

Alternatives Considered

• Having ready-to-show on the BaseWindow (see [Feature Request]: ready-to-show event for BaseWindow #42291). — I think having it on the webContents makes more sense as a BaseWindow can contain multiple webContents.
• Using did-finish-load. — Workaround for now.

Additional Information

ready-to-show already seems to be available on webContents internally:

For some reason, the following doesn't work though:

webContents.on("ready-to-show", () => console.log("ready-to-show"));

The event also isn't documented.
