What operating system are you using?

Ubuntu

Operating System Version

ubuntu 18.04

What arch are you using?

x64

Last Known Working Electron version

15.0.0

Expected Behavior

When invoking a context-menu event on the webcontents of a webview in the renderer process, the function works and does not give an error.

Actual Behavior

Since #30831 frame is sent along with the params, but frame is not serializable so can not cross from the main process to the renderer process. This results in an error being shown to the user.

Testcase Gist URL

No response

Additional Information

I'm aware that getting the webContents in the renderer process (using @electron/remote) is an antipattern. Still, I feel this is something we should not break in a minor release.

Might be duplicate of #31249?

It's a duplicate of #31249. #31259 fixes that.
