Switch to using the bottom to compute the offset. Using the top is incorrect, since
the heights of boxes can vary.

Fix a bug where the y() of the box was being used instead of the logical value, making the result
wrong for vertical text.

+        text-underline-position: under is broken
+        https://bugs.webkit.org/show_bug.cgi?id=141400
+        &lt;rdar://problem/18569583&gt;
+
+        Reviewed by Simon Fraser.
+
+        Added fast/text/text-underline-position-under.html
+
+        * rendering/InlineFlowBox.cpp:
+        (WebCore::InlineFlowBox::computeMaxLogicalBottom):
+        (WebCore::InlineFlowBox::computeMaxLogicalTop): Deleted.
+        * rendering/InlineFlowBox.h:
+        Switch to using the bottom to compute the offset. Using the top is incorrect, since
+        the heights of boxes can vary.
+
+        Fix a bug where the y() of the box was being used instead of the logical value, making the result
+        wrong for vertical text.
+
+        * rendering/RootInlineBox.cpp:
+        (WebCore::RootInlineBox::maxLogicalBottom):
+        (WebCore::RootInlineBox::maxLogicalTop): Deleted.
+        Switch to using the bottom instead of the top. Make sure the root box contributes its own bottom,
+        since the old code just ignored the root's placement.
+
+        * rendering/RootInlineBox.h:
+        * style/InlineTextBoxStyle.cpp:
+        (WebCore::computeUnderlineOffset):
+        Call the bottom function now instead of the top.
