When switching tabs, the font style transition animation does not synchronize with the indicator/content switching.
When I customize the tab header content, I adjust the font size and color of the selected and unselected items, but during scrolling, the switching speed of the font size and color does not keep up with the switching speed of the indicator and content.
Here is the effect of my question

This is my minimal reproducible example code
