trailing space in section is eaten by browser when deleting

[bantic]

In Chrome and Safari, when the cursor is at a character with a space behind it, after hitting delete once the cursor skips backward across the space:

• text is "abc d", cursor is after the d.
• Hit delete and the cursor is now after the "c" instead of after the space. The DOM still has the space but you can't use the arrow keys to move the cursor past it.

Firefox leaves the cursor after the space, as expected.

This appears to be due to Chrome/Safari not properly setting the cursor position when the text node has a trailing space. Firefox displays the cursor at the correct spot but doesn't enter text in the right place when hitting a key.
