Plone only creates object on root folder after update from 5.0.8 to 5.1.2

After update Plone from 5.0.8 to 5.1.2 I choose one site, opened news folder and tried to create a news object. I noticed that the object had been created on site root, instead of news folder. I obtained the same result on ubuntu 16 (firefox, chrome), high sierra (safari) and windows 10 (firefox, chrome and edge). It also happens if I create a new site.

There is a GitHub issue about this: https://github.com/plone/Products.CMFPlone/issues/2395

It should be fixed in the next release

@silviomarino
a workaround is to reload the page after navigation to the folder where you want to create the object.

Ok, I'm waiting for next releases, thanks.

It works. For development environment, this workaround is valid. Thank you.
