Breaking change introduced in v11.1.0

[giorgiolorini]

A breaking change related to custom css was silently introduced in v11.1.0:

CSS now injected at mount via useStyleSheet (prerequisite for nonce).

This causes a different injection order for css styles, causing the override of css variables not to work anymore unless the !important tag is added.

The fix is simple, but this is not stated in the changelog

same issue is arises, the css style gets override.
