Enter text, mark it and select
Blockquote gives some weird output.
Hello world> Hello worldHello world
It works if there is text after that is already blockquoted (for instance, selecting "For example" above and selecting blockquote works fine).
The browser I am using is Google Chrome 6.0.472.62, haven't tried it on others. Also found this error on other Stack Exchange sites (the ones I tried were Stack Overflow, Meta Stack Overflow, Super User and Meta Super User).
