Turbo not loading on Safari in production

[airblade]

I have just run into a strange problem: when I visit my production Rails app with Safari, Turbo doesn't seem to be loading.

• If I open the console and type Turbo, I get ReferenceError: Can't find variable: Turbo.

  

• Furthermore when I look at the network tab in devtools, turbo.min-6e9483ca.js is not listed.

The same site is fine with Chrome and Firefox: Turbo in the console prints the turbo object and turbo.min-6e9483ca.js is listed on the network tab. And it's also fine in development with Safari.

I'm pretty sure Safari in production worked for me a week ago but I can't think of anything that has changed since then, though evidently something has.

How can I debug this?

Safari 17.2.1, Rails 7.1.3.4, turbo-rails 2.0.5, importmap-rails 2.0.1 (with es-modules-shims 1.10.0 for legacy browsers), propshaft 0.9.0.

Hmm, quitting Safari and restarting it solved the problem. Weird.
