Is the Google structured data/rich snippets output supposed to strip out HTML from the product description?

I tested a page from my site on the Google structure data testing page, and it is displaying the HTML from the product description.

The testing tool is here: 스키마 마크업 테스트 도구 | Google 검색 센터  |  Google Developers

When I choose the examples button>products with many offers (in order to get an example with a description field) it shows plain text under the description. Just curious if this feature needs more work in order to satisfy the requirements for best results

There should not be any html in there. Please report this bug in the tracker.
