正如我之前在对How can I change the text in my desktop environment's taskbar (or in panel using Linux) for my VS Code windows?的回答中所述，这里的文本基于窗口标题，您可以通过VS Code设置进行控制。引用自defaultSettings.json：

// Controls the window title based on the current context such as the opened workspace or active editor. Variables are substituted based on the context:
// - `${activeEditorShort}`: the file name (e.g. myFile.txt).
// - `${activeEditorMedium}`: the path of the file relative to the workspace folder (e.g. myFolder/myFileFolder/myFile.txt).
// - `${activeEditorLong}`: the full path of the file (e.g. /Users/Development/myFolder/myFileFolder/myFile.txt).
// - `${activeFolderShort}`: the name of the folder the file is contained in (e.g. myFileFolder).
// - `${activeFolderMedium}`: the path of the folder the file is contained in, relative to the workspace folder (e.g. myFolder/myFileFolder).
// - `${activeFolderLong}`: the full path of the folder the file is contained in (e.g. /Users/Development/myFolder/myFileFolder).
// - `${folderName}`: name of the workspace folder the file is contained in (e.g. myFolder).
// - `${folderPath}`: file path of the workspace folder the file is contained in (e.g. /Users/Development/myFolder).
// - `${rootName}`: name of the workspace with optional remote name and workspace indicator if applicable (e.g. myFolder, myRemoteFolder [SSH] or myWorkspace (Workspace)).
// - `${rootNameShort}`: shortened name of the workspace without suffixes (e.g. myFolder, myRemoteFolder or myWorkspace).
// - `${rootPath}`: file path of the opened workspace or folder (e.g. /Users/Development/myWorkspace).
// - `${profileName}`: name of the profile in which the workspace is opened (e.g. Data Science (Profile)). Ignored if default profile is used.
// - `${appName}`: e.g. VS Code.
// - `${remoteName}`: e.g. SSH
// - `${dirty}`: an indicator for when the active editor has unsaved changes.
// - `${focusedView}`: the name of the view that is currently focused.
// - `${separator}`: a conditional separator (" - ") that only shows when surrounded by variables with values or static text.
"window.title": "${dirty}${activeEditorShort}${separator}${rootName}${separator}${profileName}${separator}${appName}",

字符串
请特别注意rootName和remoteName的描述。同时检查您是否在工作区.vscode/settings.json文件中更改了此设置，从而导致了您所观察到的问题。如果这不是原因，则可能与SSH扩展本身有关，我需要深入研究精简的源代码。
