may Fortify 1.8.4 Windows App have become incompatible to javascript lib

[bernyspeedy]

Could you please check?
we developed with version 1.8.3 of Windows App on Windows 10 and got it working with the in Browser lib pki.js.
In our Client-base, we installed version 1.8.4 and got the following error on trying an initial connection.
Thanks a lot for having a look.
Kind regards,
Bernhard
