Bug report: Script error when logon via MS Word

I experience a problem when I use MS Word to logon using Auth0. I use Chrome to logon to my application but the application uses MS Word for editing documents. This causes Word to open an Internet Explorer window with the Auth0 logon screen and while it do succed in logging users on, a script error is shown (2 errors actually):

The primary error is:
“object doesn’t support property or method ‘defineproperty’”

I don’t know which version of Internet Explorer Word is using but it is clearly a version that does not support “Object.defineProperty”.

I have been unable to find a polyfill for this error. If that exists I would imagine that I could paste it inside the Universal Login script in Auth0 for the affected tenants.

Please help.
