Oh, I see that now. What led me to ask this question was that there is an alternative implementation in `#if PLATFORM(JAVA)`, which implies that we removed the call to `stripLeadingAndTrailingHTMLSpaces` and that it is still present in the upstream.

Given that this code block now matches the upstream, the `if..else..endif` block should simply be replaced with:


    return document().completeURL(linkAttribute);


removing the `#if PLATFORM(JAVA)` and the entire `#else` block (including the old call to `stripLeadingAndTrailingHTMLSpaces`). Otherwise it will be confusing and possibly lead to merge conflicts later.
