Scrolling for pinned tabs with a title

[ongots]

Description

Add an option for the maximum number of tabs before scrolling appears (8 by default), or the ability to move the divider.

I have 21 pinned tabs and without scrolling they take up half the panel.

CSS that does what I want:

    /*   Scrolling pinned tabs   */
#root:is([data-pinned-tabs-position="top"], [data-pinned-tabs-position="panel"])[data-pinned-tabs-list="true"] .PinnedTabsBar:has(:nth-child(9)) { 
  height: calc(var(--tabs-height) * 11.3);
  overflow-y: auto;
  margin-bottom: 2px !important;
  padding: 0 !important}

#root:is([data-pinned-tabs-position="top"], [data-pinned-tabs-position="panel"])[data-pinned-tabs-list="true"] .PinnedTabsBar::after {
  position: sticky;
  bottom: 0 !important}
