[patch][needs test] JS Error during load of iframe with style "display:none" in Firefox

[tweb-ix]

During load of an iframe with "display:none" a js error occurs cause getComputedStyle returns null for elements in this iframe.

Error occurs in dojo/hccss.js line 32

Following change in dojo/dom-style.js line 49 fix the problem:

- node.ownerDocument.defaultView.getComputedStyle(node, null) || {} : {};
+ (node.ownerDocument.defaultView.getComputedStyle(node, null) || {}) : {};

corrected fix:

- node.ownerDocument.defaultView.getComputedStyle(node, null) : {};
+ (node.ownerDocument.defaultView.getComputedStyle(node, null) || {}) : {};

Ok, after massive triage, ended up with about 80 tickets for 1.11 and 400 or so for 1.12. That's a bit unrealistic, so first I changed all 1.12 to 1.13 (with the plan to move some forward to the new 1.12. Now, I'm moving some of the 1.11 tickets that are less likely to get done this month without help to 1.11. Feel free to help out in January if you want to see this ticket land in 1.11.

Ticket planning... move current 1.12 tickets out to 1.13 that likely won't get fixed in 1.12.
