Fix startup crash in Karma

The previous commit left one code path un-converted to globalThis. That
exposed a bug in Karma: Karma loads jasmine-core via <script type="module">
even though it's not an ES module. In ES modules, the value of `this`
outside of a method is undefined rather than window. The Angular dev tools
try to work around that bug by monkey-patching window to look like GJS's
window object, which worked until the GJS hack was removed in the previous
commit.
