Fullwidth character and non-fullwidth character around line break
Test passes if there IS a space after "ＦＵＬＬ" on each line in the orange box.
Tip: Check for spaces by using the cursor to highlight characters. The lower box shows the expected result.
Assertion: When displaying text the browser replaces line breaks and any adjacent spaces in the source with a single space when they fall between a character with the East Asian Width property of Fullwidth and another character that is neither Wide, Fullwidth or Halfwidth.
Each line is spread over two lines in the source text, with zero or more spaces adjacent to the line break..
