TYPO3 Core

If I work with spaceBefore everything works like expected:

<img src="clear.gif"><br />My text

"My text" ist in the next row.

But when I use spaceAfter:

1 = TEXT
1.value = Padding with clear.gif<br />
1.spaceAfter = 20
2 = TEXT
2.value = Hello

then I got:

My text<img src="clear.gif"><br />

that's wrong. I think it should be

My text<br /><img src="clear.gif">

In row 6605 of class.tslib_content.php I found the mistake. <br /> is at the end of the line instead of front.
