I have been having intermittent issues moving the web workflow to subdirectories but hadn't been able to reliably reproduce the issue. I'm now thinking it's related to this issue and the web workflow file listing is also using the current folder of the device to look for selected target folders when attempting to change to a subfolder. Essentially the Web Worfklow file listing and the devices current folder are at different locations.

#9224 (merged after this issue was reported) forces a chdir to top level when the VM is restarted. So that fixes it being "sticky", if that's the problem. But if you are using the web workflow while the program is running and has done an os.chdir(), I guess we need to fix that
