Save Filepaths remain persistent - is this a bug? If not how to pass filePaths to DAW save commands

In the following script I use the "Save Session Copy In…" DAW command to save selected tracks in an open session as a new session via the "Selected Tracks Only" check box.
When clicking the OK button, I pass the file path for the new session as described in the SFX documentation on the SF website.

Immediately following the save I call the Import Session Data command via SFX.

Here's the anomaly: I'd expect an open file dialog to appear to select the session to be imported but instead the Import Session data window opens immediately with the previously saved session.

So this leads me to believe that:
1)sessionFilePaths remains persistent (a bug?).
2) if not a bug, how do you pass a session path to an open dialog generated by a SFX / DAW command or change the persistent filePaths ?
Here's the code:

if (sf.ui.useSfx && !globalState.OPP_disableSfx) sf.ui.useSfx();
const runDawCommand = (commandName, props) => sf.ui.proTools.sfx.dawCommands.getByUniquePersistedName(commandName).run(props)

const SAVE_COPY_IN_PATH = '/Volumes/Work Drive/Dropbox/Boulevard/Copy of Talk Without Speaking-Ready For Mix/DNU-Tracks.ptx'

runDawCommand("SaveFrontDocumentCopy") // <<--- save copy in command

const saveCopyInWindow = sf.ui.proTools.windows.whoseTitle.is("Save Copy In...").first;

saveCopyInWindow.elementWaitFor()

const audioFilesCb = saveCopyInWindow.checkBoxes.whoseTitle.is("Audio Files").first;
const sellectedTrackOnlyCb = saveCopyInWindow.checkBoxes.whoseTitle.is("Selected Tracks Only").first;

if(audioFilesCb.isCheckBoxChecked)audioFilesCb.elementClick()
if(!sellectedTrackOnlyCb.isCheckBoxChecked)sellectedTrackOnlyCb.elementClick()

const okButton = saveCopyInWindow.buttons.whoseTitle.is("OK").first;

okButton.elementClick({
    filePaths: [SAVE_COPY_IN_PATH]
});

runDawCommand("ImportTracks") 

If I run other DAW commands after the save copy in command then run the Import Session Data DAW command it immediately opens to the ISD window with the saved session.
