@virtuoushub hello, help to update the version? thanks.

#115

Hi @hustcc, is the ask if this should be a patch/minor/major? I think just a patch as it fixes a bug.

---

If the ask is for a summary of these changes, #115 has all the details surrounding the bug these changes attempt to fix.

The gist of the changes in this PR is that they bring back the old logic from before #100 for those cases where the window object is not what the test framework expects; but also allow for #100 to work as expected if the window object does contain the expected properties.

Only update package.version = 2.5.2.
