Yarn link workflows broken

[KevinGrandon]

When using yarn link on packages which leverage HTML sanitization[1] in fusion-core Symbols break across packages.

STR:

• cd fusion-core && yarn link fusion-core
• cd fusion-plugin-react-router && yarn link fusion-plugin-react-router
• cd myapp && yarn link fusion-core && yarn link fusion-plugin-react-router
• Load your app in a browser.

Expected result:

• Page loads and everything works fine.

Actual result:

• See an error regarding escaped context HTML not appearing.
