Question mark is treated as independent word in the StackExchance Inbox

Question

One picture > 1000 words:

I expect the question mark to stick to the "span" word and if not enough space, both of them should be wrapped down together.

Ordinary HTML wrap is working this way, just made sure of this now. :)

Answer 1

Because the original question title had a space before the question mark, so it's treated as a separate word by the browser. Simples ;).
