Kevin Gibbons 3ed2c78600 Avoid writing to top-level vars named "top", for browser compat (#794)
The HTML spec requires browsers define a non-configurable property
of the global (window) object named "top". This makes it
impossible for a browser to successfully run a test in strict mode
if said test attempts to write to a global variable named "top".
