Yes it is fixed in the 2.6 Branch.
It happened on IE6 and IE7.
Other fixed issues with those browser was about changing page in the dashboard and list of windows that are hidden by IE. Sorry for this.
We will release a new version shortly that fixes this. Please, it is the good time to report more bugs like this. (Stuff like this are hard to test automatically).
Thanks a lot.
Please provide the solution for this problem so that we will be using it until the next release.
