[Bug]: Inconsistent Typography Font Weights in Fluent UI Implementation about fluentui

[miroslavstastny]

Thank you for reporting the issue. As you pointed out, the issue does not reproduce in the docsite, so it would need some debugging in your environment.

Here is a sandbox rendering Body1, Body1Strong, Body1Stronger: https://stackblitz.com/edit/qzpwab?file=src%2Fexample.tsx.
It should render like this:

I assume that is what you see, but does not match what you get in your application? In that case, could you please inspect your font resolutions?

Body styles use --fontFamilyBase CSS variable to set font family. For any of default Fluent UI themes, this should be set to:

'Segoe UI', 'Segoe UI Web (West European)', -apple-system, BlinkMacSystemFont, Roboto, 'Helvetica Neue', sans-serif

Font weight for Body1Strong is 600 (var(--fontWeightSemibold)). With that, Windows should use Segoe UI Semibold font:

Could you please check the font family used in your case and attach a screenshot of what you are seeing?
