Created attachment 61844 [details] work in progress, request for comments Work in progress. I made some good progress but moveParagraphWithClones grabs extra div's in many cases. It seems like I'm not giving the correct outerBlock.

Created attachment 61921 [details] work in progress 2 More progress. 5 rebaselines are added to the patch but there are 3 additional tests in /editing/execCommand/ that require rebaseline: create-list-from-range-selection.html, create-list-with-hr.html, and insert-list-empty-div.html. These tests should be dumpAsText or dumpAsMarkup tests instead and should be converted in a separate patch before this patch is to be landed. It seems like I should be making a separate cleanup patch at this point. I'll appreciate if any of you can comment on my approach / modification here.

Created attachment 62000 [details] work in progress 3 I added PersistentEditingPosition to isolate the code saving and restoring selection. It stores a VisiblePosition and returns the VisiblePosition when available. When the deepEquivalent node gets detached from the document and the original VisiblePosition becomes invalid, it restores the position using the range length.

+Roland I'll appreciate if you can comment on PersistentEditingPosition and if there's any similarity to what you were proposing few weeks ago.

I just realized that my patch might cause a significant performance regression since TextIterator will iterate through all the nodes starting at the editable root to find the correct location. I need to figure out an alternative approach here.
