描述

Originally in https://github.com/microsoft/vscode-pull-request-github/issues/4872#issuecomment-1573555380

Here is what I see happen:

  1. Open a folder
  2. Have an extension that creates a webview view
  3. Keep the webview view open
  4. Add a folder to the workspace, which causes the extension host to be restarted.
  5. The extension's deactivate gets called as expected. In deactivate the extension disposes of the webview view provider.
  6. With this dispose I would expect the webview view to hide, but it does not.

You can easily reproduce the above using the GitHub Pull Request extension with the steps linked from the original issue.

研究方向
Investigate the webview view provider disposal mechanism in VSCode. Look at the extension host restart sequence and the lifecycle of webview views. The issue mentions that dispose() is called but the view does not hide. Check files related to webview view rendering and extension host communication. Consider looking at the linked original issue for more context.
