Laravel Telescope: SVG icons not rendering on dev server

I've got telescope running fine on my local machine running valet. On my dev server running my project in docker - telescope is not working properly.

The first obvious sign is that the SVG icons don't render - I've tried it in 3 browsers and it's the same - icons render with my local telescope not the remote one.

Also, it appears that the JS element listeners on the Commands, Requests, Logs, etc elements aren't running properly. Initially, I can click on new nav items and the page reloads instantly. But if I click on one that is enabled but the XHR returns an empty list - then the automatic page reloading breaks: when I click on a new nav-item it doesn't automatically load that page - the URL changes, but the XHR fetch for the previous command keeps running until I hit reload. Once I hit reload I can click new nav items until I click one that returns zero items and it breaks again.

The CSS and JS assets are being loaded.

I'm wondering what could be causing it or how to go about debugging it.

Cheers
