Issue with @import after update to 1.3.3 and / or WordPress 6.4

I get this after updating (did not appear before):

Any idea where this is coming from?

Hello @FZwo,

Looking at the offenders list, this is related to the Dark Mode switcher which imports that small easing library.
If you prefer, you can include it directly through a Cwicly stylesheet (or enqueue) to bypass this error.

Cheers,

ah, ok, already guessed that it comes from there. I think I can leave it as it is, impact on performance seems to be low
