The previous version in which this bug was not present was

No response

Description

Using external SCSS files, all mat.*-overrides() work and generate tokens, but using inline styles, it does not work.

NOTE: I've created 2 Stackblitz projects with and without Tailwind CSS. and It's not related with it, because we get the same result

Reproduction

StackBlitz link with tailwind: https://stackblitz.com/edit/stackblitz-starters-grfvrcyg
StackBlitz link without tailwind: https://stackblitz.com/edit/stackblitz-starters-dyspj7b7
Steps to reproduce:

1. Open Stackblitz link
2. Both components have same styles, but one is inline and the other in a file

Expected Behavior

Both inline and style files should works and generate the same styles code

Actual Behavior

Inline does not generate tokens

A component with inline style, generates empty host styles

A component with external style file, generates host styles well

Environment
