Bug Description

Steps to reproduce in master:

1. Create a page
2. Click "Text box" in the content editor
3. Enter "<script>alert(1);</script>" without the quotes in the "Block title" and save the block
4. Click "Text box" in the content editor again. (Note: do not drag/drop a text box, only happens if you click)

What happens:

An alert is popped up on the page.

What should happen:

Alert should not be shown.

Proposed fix is attached as a patch. Note that while the attached patch fixes it for me there are other references to h2.title in that file, so you might want to confirm that this fixes it properly.
