Search does this in a different sort of way...

Notes to self or whoever takes over search and fixes this

• Context menu context is set here:

  vscode/src/vs/workbench/contrib/search/browser/searchView.ts

  Line 979 in db865c3

  getActionsContext: () => e.element,

• But it's supposed to be a ISearchActionContext as here

  vscode/src/vs/workbench/contrib/search/browser/searchResultsView.ts

  Line 327 in db865c3

  templateData.actions.context = { viewer: this.searchView.getControl(), element: fileMatch } satisfies ISearchActionContext;

• But the real context is determined totally dynamically, which you see here

  vscode/src/vs/workbench/contrib/search/browser/searchActionsRemoveReplace.ts

  Line 103 in db865c3

  const elementsToRemove = getElementsToOperateOn(viewer, element, configurationService.getValue<ISearchConfigurationProperties>('search'));

• Not sure what the extra complexity is vs having this whole set in the context. In the explorer it looks like this

  vscode/src/vs/workbench/contrib/files/browser/views/explorerView.ts

  Line 661 in db865c3

  getActionsContext: () => stat && selection && selection.indexOf(stat) >= 0
