Small hashtag issue

Hey team,

Just discovered a tiny hashtag issue at the stream filter page. Maybe it is deliberate, not sure, but here's how it looks like and how you can replicate it:

Click on an existing hashtag link in the stream, so you will be redirected to the stream filter page.
If you hit the sharebox, the predefined keyword will be there. If you leave your cursor at its original place (before the keyword), it's fine, works great as intended.
When you move your cursor after the keyword, your stream item will gain an extra # besides the hashtag, and there won't be any spaces for example between the hashtag & your own words.

Hope you can follow my drift, but I attached a screenshot, as well as a video to help you out tracking this down. Check it out pls: http://screencast.com/t/TlHnAJmO5f
Let me know, if this a normal phenomenon, or an existing issue Probably it's just a typo in the source code

One more closing question: at hashtag page, you cannot close the sharebox. Is that right by the way?
Hope this thread helps. Thanks in advance.
Regards,

Attila
