Header details messed up on a multi step user journey

[nccgroup_avi]

Whilst trying a multi step user journey on WPT, I observed something weird. Please see below:

Code:
navigate http://www.bbc.co.uk
execAndWait document.querySelector('.orb-nav-sport a').click()

Now to reproduce the issue, please follow these steps:
1. Go to http://www.webpagetest.org/result/140908...s/#request
2. Click on 'Request #1'

Observation:
Only the Details tab shows correct results. Both the other tabs (Request and Response headers) are incorrect. Is it a known issue?

Workaround solution:
use combineSteps - http://www.webpagetest.org/result/140908...1/details/

Hasn't been looked at yet but it's on my radar.
