Folder doesn't open in in the open/save dialog

[ttrafford7]

Describe the bug
While the open/save dialog is active and you open FS and search for a folder, press enter, it will open in a new File Explorer window and not in the active Open/Save dialog (first time it works but then it stops)

To Reproduce
Steps to reproduce the behavior:

1. Open an Open/Save dialog
2. Launch FS, search for a folder, open it
3. First time it works and then it breaks

also it was with fluent search broken indexer selected, I think it doesn't work there even the first time
