Pinned tabs look weird when many tabs are open

When many tabs are open, pinned tabs look like this:

As you can see in the image above, the favicon of the pinned tab is rendered above the text of non-pinned tabs. I've only made small tweaks to the original minimal-function-fox (colors and rounded borders), so I think this "bug" may be affecting other users as well.

Thanks for developing this awesome config! Made my internet browsing much more focused and aethetically pleasing.
