Operating System: Windows 10 Updated to latest Patch

REPRODUCTION CASE

Poc

Open the below html file. Click on save the jpg file
It will show the Directory Picker Dialog
Approve them
You can now see the Bat file is saved into the disk without any popup

If we can specify the exact folder to open via showDirectoryPicker Method Then This will have a higher impact which of similar to my above report

We can trick the user to hold enter for 2 Sec this will Accept all the dialogs and save the file.

I have tried open the direct sub folder but it is not possible so it needs User interaction to download a file
