Split <object> tests further to reduce timeout risk

 // global async_test, assert_equals

 // This test generates a couple of scenarios (each a TestData) for
 // sizing SVG inside an inline <object> and has a simple JavaScript
 // sizing implementation that handles the generated scenarios. It
 // generates a DOM corresponding to the scenario and compares the laid
 // out size to the calculated size.

 // The tests loops through different combinations of:
