Expected Behavior

• Create a window from the renderer via window.open, and override the options in the main process to set vibrancy: "titlebar" (though any valid vibrancy value seems to reproduce this).
• Right-click on the created window.
• The normal right-click action (possibly a no-op) occurs.

Actual Behavior

The app crashes.

Additional Information

This reproduces on 32.2.6, 33.2.1, and 34.0.0-beta.6. It does not reproduce on 32.2.5, 33.2.0, or 34.0.0-beta.5.

I made a local build from v32.2.6 and tested. Reverting #44761 (or more properly, its v32 backport #44798 / 85a3ed3) fixed the crash, but applying #44940 did not fix the crash.
