Posting on Tumblr is broken

[nex3]

Composing a post on Tumblr seems to be broken when HTTPS everywhere is enabled on Chrome. This just started happening today, so I suspect it's an issue with version 2014.4.16. To reproduce (assuming you have a tumblr account):

• Go to http://www.tumblr.com/blog/<your blog>.
• Click "Text" on the big bar with all the buttons.
• Notice that the screen goes dark but no text box appears.

I'm using Chrome 34.0.1847.116 m on Windows 8.1.

Similarly, following a Tumblr blog, reblogging a post, or editing content is broken. Tumblr displays a few buttons at the top-right corner of the page. Apparently, these are loaded by an insecure script which is blocked if HTTPS Everywhere is enabled. As of 2 days ago, a shield icon appears in the status bar, displaying a message that the page contains a script from insecure sources (translated from German) and a button to load the script. However, clicking on the button has no effect. If HTTPS Everywhere is disabled, the Tumblr UI loads fine.

Confirming this issue, happens to me also.
Disabling the site rule fixes the issue.

Ok, I am going to fix this by reverting to the version of Tumblr in the 3.4.5 release.
