[Karl Dubost]

Steps to reproduce:
1. with macOS Ventura on Safari Version 16.0 (18614.1.19.1.5)
2. Go to https://mozilla.github.io/translate/

Expected:
page loads and menu are initialized.

Actual:
drop down menu stays blank and the page is inactive.

The console displays:

```

the message seems to be generated by
