<br> does not get deleted when inlined after some non-textual content.
https://bugs.webkit.org/show_bug.cgi?id=120006 Patch by Arpita Bahuguna <firstname.lastname@example.org> on 2013-08-23 Reviewed by Ryosuke Niwa. Source/WebCore: deleteSelectionCommand does not handle the case when a <br> element is inlined after some non-textual content (input controls, image etc.). When doing a back-delete at the start of a line following such a <br> the two contiguous lines should merge and the <br> should get deleted. Currently, even though the <br> is deleted, another placeholder <br> is incorrectly inserted at the same point, thus effectively there is no change. We are incorrectly computing the inline <br> to be at the start of an empty line even though the line is not empty. Test: editing/deleting/delete-inline-br.html * editing/DeleteSelectionCommand.cpp: (WebCore::DeleteSelectionCommand::handleSpecialCaseBRDelete): Adding a check to verify that the inline <br> is not on an empty line if the end node is not a <br> element itself and it's previous sibling is the start <br> element. Basically we check whether there is another node (end node) following the <br>, that the node is not a <br> itself, and that the end node's previous node is the start <br>. LayoutTests: * editing/deleting/delete-inline-br-expected.txt: Added. * editing/deleting/delete-inline-br.html: Added. Added a testcase that verifies that the caret is placed at the correct position after performing a back-delete operation. * editing/deleting/delete-before-block-image-2-expected.txt: * platform/mac/editing/deleting/delete-br-004-expected.txt: * platform/mac/editing/deleting/delete-br-005-expected.txt: * platform/mac/editing/deleting/delete-br-006-expected.txt: * platform/qt/editing/deleting/delete-br-004-expected.txt: * platform/qt/editing/deleting/delete-br-005-expected.txt: * platform/qt/editing/deleting/delete-br-006-expected.txt: Rebaselining existing tests.
