On windows 10, i could not replicate the issue you have mentioned. i tried deleting folders via share and restore them back, i could see and navigate the items in the folder via webdav after restoration.
I tried deleting the folder from webdav interface and restored it back via webdav. I could see and navigate the folder and its content via both share and webdav.
I did noticed that, when i restored the folder via Share and tried to access the folder via webdav, it was not clickable immediately and took few seconds to a minute to allow navigating the folder again. But i was not able to replicate the visibilty issue at all.
Can you try investigagting the restored folder nodeRef via node browser and see if you can notice any thing special there? Also just try updating some properties of the folder via share and see if it starts showing
