Hi Numan,
I put together a quick hack to verify this is the issue. I am not
sure it covers all corner cases, and I am not entirely happy with
the approach either. However I tried several alternatives and
this seems to be the cleanest so far.
Give it a shot and let me know. If I find more time in the next
couple of weeks I will try to work on a proper fix.
You can find the patch here:

Cheers,
Eelco
