Cannot tab past CKEditor when it is in read only mode

[Teresa Monahan]

• Open _samples/readonly.html.
• Click the 'Make it read-only' button and then tab through the page until the editor gets focus.
• Tab again to move focus to the button below the editor.

Problem: It is not possible to Tab / Shift+Tab once the read only editor has focus.

This is also an issue in CKEditor 4.0 if the editor contains some focusable element. In this case, pressing tab when the editor has focus, moves focus to the first focusable element inside the editor contents and then it is not possible to Tab / Shift+Tab.

Reproducible from CKEditor 3.6 rev. [6904] (when readonly was intrduced).

CKEditor 4.x needs focusable element like link to get error reproduced.

Pity we cannot simulate real DOM events for testing purposes.

In v3, this has been fixed with [7681].

Replying to fredck:

In v3, this has been fixed with [7681].

It's not properly fixed in 3.6.x as in 4.0.1

When we are navigating forward, when we press tab after reaching editor body, moving the focus to element outside editor body instead of the focussable element(link) in editor body. Also when navigating back when we press Shift + Tab after reaching focussable element(link) in editor body focus moving to element before editor body instead of editor body.

Could you please re-open the ticket and fix it in 3.6.x as the way it works in 4.0.1

[Frederico Caldeira Knabben]

This is a persistent difference that can't be worked-around because of the totally different DOM structures and focus strategy present in v3 and v4.

We can say that both behavior are good. The issue may be only the fact that different versions behave differently, but that's something we'll have to live with.
