Scroll is disabled on Connector Set Up page on a specific doc panel width

[erica-airbyte]

Environment

Cloud / OSS

Current Behavior

The connector set up page will not scroll when the doc panel on the right is at a specific width. This is easy to reproduce when dev tools is open. (recording can be provided on request).

You can scroll the knowledge base on the page but not the connector set up.

Expected Behavior

Be able to scroll a page when dev tools is open.

Steps to Reproduce

1. Select "Set up Source/destination"
2. Choose source/dest. to set up (Bigquery is a good one since it has a long set up page)
3. On the connector set up page open up developer tools and try and scroll down the page.
4. The page scroll is not possible.
