Twenty Eleven: responsive design does not drop sidebars entirely

[devinreams]

I've set up a Twenty Eleven theme and using the "Home" page template:

• added a "Text Widget" to the Default Sidebar
• enabled "Auto add paragraphs"
• entered text, two line returns, and text (i.e.: 2 paragraphs)
• loaded the home page
• resized browser down to size where sidebar (#secondary) should responsively 'drop' below main content (#primary)

Issue: the first paragraph in the text widget is still floating right over the main content area, second paragraph and remaining widgets appear beneath as expected.

Expected behavior: the sidebar or widgets are cleared properly to drop down below. ​http://d.pr/BCQ6

Worked around by adding "clear: left" to .widget in style.css (line 1536 at r17917).

Not sure the "best" solution here, I leave that to the experts to verify my approach above.

Add clear:left to .widget for responsive design collapsing

This does only happen, if no title is given. h1 for the title has clear:both which is missing.
