test(ivy): account for inconsistent attribute order (#34305) 

We've got some tests that assert that the generate DOM looks correct. The problem is that IE changes the attribute order in `innerHTML` which caused the tests to fail. I've reworked the relevant tests not to assert directly against `innerHTML`.

PR Close #34305
