There's a bug with Double Click To Open: if you double click on a folder which is already opened, it will be close and then reopened. This is due to both ItemTapped and DoubleTapped being raised. The only way to fix this (Microsoft Docs) is to introduce another timer like we do for DoubleClickToRename. I'll try to work on that, should I push the fix here or in a different PR?

A separate PR, thanks!
