Unknown tags in the "updates notes" (launcher 0.2)

In the "updates notes " section of the launcher, we can see unknown tags like "<vnoscript>".
These one don't appear on the official Tumblr page.
Here is a screenshot as attachement.
I've seen this bug has been reported here : https://mojang.atlassian.net/browse/MC-13596
I'd like to show you Mario-Fan is not the only one who can see this bug.
Thanks for your attention.
