Tabs: Regression in scrolling behavior when updating to version 14

[michael-iden]

Expected behavior Contents of pharos tabs would scroll while tabs would remain fixed at the top of the page

Actual behavior Contents were unable to scroll at all given surrounding CSS

Steps to reproduce the issue

1. Use pharos < 14 and generate a layout where tab panel scrolls
2. Update to pharos 14
3. See that the tab panel stops scrolling and the contents are all fixed on the page

Screenshots or code Here is a video showing the current behavior in prod when using pharos < 14 and then making the CSS change manually that was done in Pharos14. After making the change I attempt to scroll but its not handled https://github.com/ithaka/pharos/assets/13315416/9ed17f5f-c51c-4b61-985f-d01984206ff6
