Keep pins on vertical tabs sticky

hi, I have been using the Arc browser for a few months and really enjoy their browser experience. However, Arc is not open source and thus I have privacy concerns to continue using their browser. That is why I am defaulting back to Brave.

That is why, I am am suggesting to make pinned pages on the vertical tabs bar sticky. It functions similar to the bookmarks bar but instead they are pinned to the top of the vertical tabs bar.

If you have used Arc before you will understand why I am requesting this feature, it keeps pages tidy and neat on top and you do not have to re-pin your pages every time you restart your computer.

This feature is already present:

Observe that the pinned tabs appear and persist above my vertical tabs.
