"My work" shows issues and PR's on repos that are not mine

### Short summary

_No response_

### Affected version or release

v1.0.15

### Installation context

Windows

### What happened?

I see other repos than expected on "My work" --> "All" and it is not clear why. For me it is `microsoft/vscode`, which I do watch with "participating and mentions", but I do not see these issues in my feed for example. Screenshot below.

### Steps to reproduce

_No response_

### Expected behavior

Tell my why I see this repo, and how to hide it from this view. I can filter it, but that seems an extra step/

### Additional context

在 Windows 上使用 v1.0.15，通过打开 “My work” → “All” 并观察 microsoft/vscode 这样的已关注仓库来复现该报告。跟踪仓库如何进入此视图以及筛选如何工作；完成的标准是该视图能够说明仓库为何会出现，并提供无需额外筛选步骤即可将其隐藏的方法。
