Created attachment 223439 [details] layout test that fails The nested region with the float property is rendered as a block, not as a float.
Created attachment 223440 [details] layout test expected result
Created attachment 223973 [details] Test This bug is invalid. The problem in the attached test is that the nested region also has the outerContent class, which causes it to be directly flowed into the outer flow, making it a sibling of its parent. Simplified test and added it to the regions layout tests.
