I'm not sure when this was introduced, but it's not the case on 1.0.x.
Edit: title corrected from 1.1.8 to 2.0 dev.
Wow .. that is ugly. To fix in 1.1.9 (and check in 2.0)
Broken in 2.0 but fixed on my local ... still to look at 1.1 but its due to shared styles between topic listing and search results.
It should be fixed here for 2.0 ...
For some reason I am not seeing this issue on my local 1.1.8?
The topic title is wrong, my bad. ;)
