While in split view mode add a control for setting/changing the percentage of screen/frame uses. Where the combination of the header list and reading pane == 100% thereby ajusting the reading pane to 70% the header pane also adjusts to 30% of the space alotted to both. With this setting I can accommodate troublesome emails that won't display properly.
