Issue Summary

The font size on Jira boards changes unexpectedly from larger to smaller after the tab has been left open and inactive for a few minutes, and then interacting with the cog wheel and hovering over "General Settings.

• Font change perceived from tickets while exploring the new nav, but it is not always triggered by this specific action.

Steps to Reproduce

1. Open a Jira board with work item cards displayed, left side bar open, grouped by epic.
2. Leave the tab open and work on other things in different tabs for about 10 minutes.
3. Return to the Jira tab, open the cog wheel, and hover over "General Settings."
4. Observe if the font size changes to a smaller size.

Expected Results

The font size should remain consistent regardless of inactivity or interaction with "General Settings."

Actual Results
