Description
In the Knockout 3.5.1 release, there was a change to the components/defaultLoader.js that is breaking compatibility issues with IE <= 8 due to the use of reserved word default.

if (module && typeof module === 'object' && module.__esModule && module.default) { module = module.default; }

My suggested fix is to change from dot notation to bracket notation.
if (module && typeof module === 'object' && module.__esModule && module['default']) { module = module['default']; }

I have tested this with IE 8 and it seems to fix the issue.

Expected Behavior
Compatibility with IE <= 8

Actual Behavior
Unable to load page in IE <= 8

Steps to Reproduce the Problem
Open page using templates and knockout 3.5.1 in IE <=8 (or 11 in compatibility mode)

Specifications
Version: Knockout 3.5.1
Last Working Version: Knockout 3.5.0
Platform: Windows 10
Browser: IE <= 8
