Does Theia support workbench.action.keepEditor command?
when i using sarif-viewer vscode extension, it prompt me
Command with id ‘workbench.action.keepEditor’ is not registered.,and i see in packages/plugin-ext-vscode/src/browser/plugin-vscode-commands-contribution.ts,

@anduodefeng thank you for the discussion, the command workbench.action.keepEditor is not yet implemented, nor is pinning editors: https://github.com/eclipse-theia/theia/issues/9326.
