**Short description of error**
When you create a new viewlayer and try to hide a collection from the viewport (alt-click on eye-icon), it only works in the current viewlayer. After saving the blendfile and re-opening it works as expected. Maybe some missing update flag or so?
**Exact steps for others to reproduce the error**
Since saving the blendfile forces all the flags, updates etc. and fixes the error I can't upload a sample file.
But if you follow these steps you should be able to reproduce the issue in factory startup:
1. create a new Viewlayer ('View Layer.001")
2. Alt-Click on "Collection" eye-icon (-> everything inside Collection is hidden)
3. Switch back to "View Layer"
--> Everything is visible, even though it shouldnt be. Also, note how the text in the outliner is not greyed out.
