Add support for Safari browser

Here's a list of issues found on Safari 3.1.2 (525.21) 4.0.4 (531.21.10):

1. underline + strike through doesn't work when the tool bar buttons are used
2. can't move the caret before the first letter of styled text (bold, italic, etc.) (not supported)
3. can't place the caret at the start of an in-line element (click bold button when there's no selection but the caret) (not supported)
4. selection is collapsed at its end when an operation is impossible (underline+strike through, subscript+superscript, etc.)
5. subscript + superscript doesn't work (only one of them is allowed)
6. remove sub/superscript doesn't work
7. blur/focus problems (by clicking on unordered list 3 times the rich text area looses the focus)
8. rich text area is blurred on load even when the browser window has focus
9. problem with empty blocks (paragraphs, headings); a BR might be needed; as a consequence empty paragraphs and headings can't be created
10. insert two symbols; the second is inserted before the first
11. shift+tab on a first level list item blurs the rich text area
12. delete table blurs the rich text area
13. refresh macro doesn't focus the rich text area
14. macros are not detected
15. cannot select or resize an image with the mouse (resize handlers missing) (not supported)
16. element meta data is not handled properly, making links, macros and images almost unusable
17. pressing enter in complex list item doesn't create a new list item but splits the block containing the caret (default behaviour)
18. Safari adds classes to some elements: class="Apple-style-span"
19. pressing backspace keeps the style but not the markup: deleting a heading with backspace keeps the heading style but not the h1 markup
20. edit in full screen doesn't work
21. sometimes the editor fails loading and the error console displays "Null value"
22. the saved content is ignored: the rich text area is empty after the editor finished loading

Marius, is this list valid for Safari 4 too or are there more things to fix?

Another issue with Safari 4 seems to be the absence of focus in dialog box text fields.

For instance, if I do the following:

• write some text
• select a word
• click on the link menu
• click on the web page item

Then the dialog box appears, and I would expect the focus to be by default in the field where I'd like to enter the URL.
Vincent told me it's working elsewhere (ie. in Firefox) but is probably not working in Safari 4.

(I'm using Safari 4 on my Leopard MBP)

Another issue related to my previous comment.

When I follow the same scenario as previously, I select a word to add a link to it, but the decide to not add any link, and directly close the dialog box with the cross, then I got back to the normal editing view, but my selection has disappeared.

I think the selected text should stay selected, even if I don't add a link.

Guillaume, I can reproduce the focus problem but the selection is preserved when I close the link dialog using the cross. I'm testing with 4.0.4 (531.21.10) on Windows XP.

The glass panel ( http://code.google.com/p/google-web-toolkit-incubator/wiki/GlassPanel ) steals the focus from the dialog box even if the dialog box focuses its first input field using a deferred command.

The missing focus issue has been fixed by XWIKI-5857.

Closing this issue for 3.0M3. From now on Safari/Chrome issues should be reported separately.
