 As @melchoyce mentioned in slack, the issues here are more to do with the
 combo of the JS for docking the titles + grid compatibility issues.
 Technically grid is supported in IE11, so we're keeping the grid for the
 layout of header + section, but switching to a flex layout for the items
 themselves. This, plus some updates to the title-length-detection
 javascript seems to fix the layout issues in IE11 and Edge (by my testing
 on browserstack) - it would be great to confirm that with "real" use of IE

 See [attachment:42545.diff] for the patch. I also ran `grunt postcss:core`
