Stop from the shortcut, menu or Find Action stopped the selected configuration's process whenever it was running, so with several processes there was no way to pick another or stop them all. Like IDEA's Stop it now stops the only stoppable process or lists them all with Stop All; the run widget's stop button keeps stopping the selected configuration and the Run tool window its active tab.
With several sessions running, the toolbar's Rerun and Stop could act on a different configuration than the selected one: when the selected configuration had no matching run session, the widget fell back to the most recently started session of another configuration; and debug sessions did not record the configuration they were started from, so a configuration being debugged never matched and a running npm session took over the buttons.
The widget, Run (Shift+F10) and Stop (Cmd+F2) now target the selected configuration's session, whether it was started with Run or Debug (the most recent when both exist); Rerun of a debug session reruns it in debug. When the selected configuration is not running, the widget offers Run / Debug for it, and Stop remains available for the other running sessions (with a chooser when several are running). Debug sessions keep their originating run configuration. In a focused Run or Debug tool window, Stop still stops the selected tab's process.
