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    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?
