Regarding the issues that arise when using Markdown controls in WINUI3

[qihui-liu]

I encountered a strange problem when using the markdown control in Winui3 under arm64.
When inputting content into markdown through code, I encountered a situation where markdown does not display the content, but I added a visible text box that displays the content.
This is an occasional problem. I can't be sure.
I created a new project with only textblock, markdown, and button, which runs in a threaded manner but still displays normally. It's really confusing.
Has anyone encountered the same problem before?

Sorry, this was a misunderstanding. I have found the reason and I don't know which idiot added the visibility binding that caused it
