Describe your issue When generating ring class name tailwind adds:

var(--tw-ring-inset,) 0 0 0 calc(40px + var(--tw-ring-offset-width)) var(--tw-ring-color, currentcolor)

see extra comma after --tw-ring-inset, because of that it does not seem to work in older browser which are in supported by Tailwind like Chrome 111/118 I tested on latest Chrome 139 and it does work.

Fix seems to be remove extra comma.
