When a span element's opening and closing tags are on different lines in the HTML and there is no content in the span, it should be imported as a single space.

For example, the following HTML:

test,<span>
</span>test<span> 

should be imported as

test, test


Note: If there is content in the span that is split between the lines, it is correctly imported:
test,<span>a
</span>test<span> 

results in

test,a test
