Kibana version: master (6.0.0-alpha1)

Elasticsearch version: master

Server OS version: Windows 10

Browser version: IE 11

Browser OS version: Windows 10

Original install method (e.g. download page, yum, from source, etc.): dev testing

Description of the problem including expected versus actual behavior: There are 4 tests that fail on Windows/IE but pass on Windows/Chrome.

A few other tests also fail, but they were timeouts on the 10s timeout setting and I submitted a PR to change that timeout to 20s.

Steps to reproduce:

1. npm run test:dev
2. When IE 11 browser opens, create new tab and paste
   http://localhost:9876/debug.html?grep=JSON%20input%20validation
3. Windows 10, IE 11 output;
