Issue Summary:

Steps to Reproduce

1. Install an app using the Atlassian components (ex, @atlaskit/breadcrumbs)
2. Open a page that lets the Connect app render any text

Expected Results

The text size within the Connect iframe aligns with the outside of the iframe areas.

Actual Results

The text size within the Connect iframe doesn't align with the outside of the iframe areas.

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
