Thanks! I'll report this to the developers, this had been previously reported by someone using a beta browser and we couldn't reproduce it in a stable release, I'll use this info to help them isolate the issue. Thank you.
The development team have looked into this and they cannot reproduce it at all. Do you have any extensions that could be interfering with the forum in any way? I'm going to keep an eye out for any further reports and if any further reports do happen (or you can confirm it's not caused by extensions and provide a way to reproduce) they'll look into it again. Thanks!
