TextBlock.Style end tag has 2 > symbols but xaml not seeing them- Causing the symbol to be shown as part of render.

_This issue has been moved from [a ticket on Developer Community](https://developercommunity.visualstudio.com/t/TextBlockStyle-end-tag-has-2--symbols-/10481103)._

---
The GT symbol in the end tag of TextBlock.Style is rendered when it is entered twice at the end of the endtag as shown in the screenshot. I thought the render was an error in the Trigger since the text is supposed to be changed to Yes! when the Checkbox is checked. It would change the color of the text 'NO' to green but would not change the text to 'Yes!' as per the code.
