>+
>+        The 'white-space: break-spaces' only adds breaking opportunities after
>+        a white space character. However, it's possible to break before the
>+        first space after a word when the feature is used in combination with
>+        other properties, like overflow-wrap.
>+
>+        However, breaking before the first space should not be allowed if
>+        there are previous opportunities. We wrongly assumed that we had to
>+        consider these previous breaking opportunities if the proper combination
>+        of line breaking properties is being used, so that breaking before the
>+        first space after a word is allowed.
>+
>+        This wrong assumption caused several issues, like the one described in
>+        the bug, that lead to incorrectly break before the first space even
>+        though there are previous opportunities, either white spaces or between
>+        letters.
>+
>+        Theses issues have been analyzed [1] by the CSS WG and finally agreed on a
>+        expected behavior, represented in the Web Platform tests added in this
>+        patch.
>+
>+        For the later case, of considering previous opportunities between
>+        letters, we have a seperated issue #952254, so the tests covering such
>+        cases will be added to the TestExpecations as Failure entries.
