Bug 26816 – Selection changed by indent

• Status: RESOLVED
• Resolution: FIXED
• Component: HTML Editing

[Julie Parent]

This is a follow up from https://bugs.webkit.org/show_bug.cgi?id=21712, so just repeating those repro steps here.

Repro steps: Go to http://www.mozilla.org/editor/midasdemo/
1. Type one<enter>two<enter>three<enter>four
2. Select all, click on ordered list
3. Select "two" and "three" and click indent, forming a sublist.
4. Select "three" and click outdent, joining three back with the outer list.
5. Select "three" by double clicking and click indent, bringing three back into the sublist.

Result: "three" is no longer selected, instead the last "e" from three is selected, and the "fou" in four on the next line is selected
Expected result: Selection should be unchanged, "three" should still be selected.

I think this was a result of http://trac.webkit.org/changeset/45316

Yes, I have become aware of this problem right after submitting the patch.  This is due to changeset 45316.  The fact that indentRegion stores the index of selection and restores it later is to with selection being changed.  I believe restoring selection is only needed because of what moveParagraph does.  Right now, I'm trying to avoid using moveParagraph at all since this function is causing a lot of problems.

This patch is rather large to review.  I certainly can't do so tonight, and I think you'll have trouble finding a reviewer for a patch of this size. :(

Should have a bug:
+    // FIXME: we need to deal with the case where there is no li (malformed HTML)
+    if (!selectedListItem->hasTagName(liTag))
+        return false;


024 \ No newline at end of file

Needs an arg name for the Node*:
 59     void indentIntoBlockquote(const VisiblePosition&, const VisiblePosition&, RefPtr<Element>&, Node*);

Looks fine otherwise.  Thanks!
