Regression from 1.1.X: BorderContainer Splitter resize is extremely slow when resize reducing pane containing iframe

[Jared Jurkiewicz]

Regression from 1.1.X: BorderContainer? Splitter resize is extremely slow when resize reducing pane containing iframe.

The problem occurs when trying to compress an iframe contained within a pane. Stretch the pane left (increase), expands fine and quickly. Do it to the right (reduction), compression is very slow and flaky.

This problem occurs on 1.2.X and trunk (1.3). It does not occur on 1.1.X, therefore, regression.

There is a testcase attached that consists of two files, test.html and test2.html. test.html does the basic layout and defines the iframe that loads test2.html.

They go in the root of you dojo extract. It will work fine on dojo 1.1.X, but work terribly on 1.2.X or later.

Testcase will follow.

this is the exact same issue fixed in #8234, but that is for splittercontainer (rather than bordercontainer itself), just want to point this out, maybe useful

Thanks, Cougar. Yes, Bill pointed this out and suggested a separate style. We should leave SplitContainer? as-is, since we don't want to carry additional style rules for deprecated code. See [16094] This still does not work in IE8 for some reason.

(In [16216]) Undo regression from [16094]. Fixes #8332, Refs #8287

Isn't this fixed by the above checkin?
