401019 - Can't tab through focusable elements in design mode iframe

Status: NEW

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Chris Pearce [:cpearce (Not reading bugmail)]]

Attachment: Testcase

If you have a design mode iframe with 2 or more focusable elements in it (like a link, or a button) you cannot cycle the focus. You press tab and the focus enters the iframe, it focuses the first focusable correctly, but then subsequent tab presses you cannot move to focus the next focusable.

Steps to reproduce:

1. Load testcase.
2. Press tab until the first link1 in the iframe is focused.
3. Press tab again.
4. Note that link2 gets the focus.
5. Press tab, note that link3 does not get the focus.

Expected result: link3 should get the focus.

The problem here is that the search for the next focusable begins from the last selection/caret position. The caret is not moving with the focus, and so the search for the next focusable is beginning again from the caret at the start of  the iframe content.

Don't see any bug here. Links and form elements in designmode documents not being focusable is intentional behaviour.
