@gabbybilka as an FYI.

I'll link this up to #12400. We'll probably need to track this upstream too. I'm not sure there's immediately any way for us to control the styling of the focused tab such that we can prevent it from getting bolded like that.

I'm gonna tag this up for discussion - honestly, we've been shipping with this for a year now, and there hasn't been an overwhelming amount of complaints. I didn't love it at first, but the bold text does add a little bit more emphasis to help ID the active tab. We may as well just leave this.

Yea our consensus was that if anything, this should be filed upstream over at https://github.com/microsoft/microsoft-ui-xaml.
