This seems to be unintentionally fixed by the previous CL because there is no
line break in this test case.

 testRemoveFormat('<code>hello <strong>world WebKit</storng></code>', selectFirstTwoWords, 'hello world<code><strong> WebKit</strong></code>');
 testRemoveFormat('<acronym><tt><mark><samp>hello</samp></mark> world <sub>WebKit</sub></tt></acronym>',
-    selectFirstTwoWords, '<mark>hello</mark> world <acronym><tt><sub>WebKit</sub></tt></acronym>');
+    selectFirstTwoWords, '<mark>hello</mark> world<acronym><tt> <sub>WebKit</sub></tt></acronym>');
 testRemoveFormat('<b><div>hello world</div></b><div>WebKit</div>', selectLastTwoWords, '<div><b>hello </b>world</div><div>WebKit</div>');
 testRemoveFormat('<q><b><div>hello world</div></b>WebKit</q>', selectLastTwoWords, '<div><q><b>hello </b></q>world</div>WebKit');
 testRemoveFormat('<q><b><div>hello world</div></b>WebKit</q>', selectSecondWord, '<div><q><b>hello </b></q>world</div><q>WebKit</q>');
