When adding a disk to a virtual machine, and changing the storage class field, the user interface goes blank. This seems to happen when the newly selected storage class does not have the access mode and volume mode that were set for the previous storage profile.

Always

I'm using OpenShift Data Foundation, which has a storage class "ocs-storagecluster-ceph-rbd", which offers volume mode = block and another storageclass "ocs-storagecluster-cephfs", which offers volume mode = file.

1. Go to a VM -> configuration -> storage -> add disk
2. Select "Blank (creates PVC)"
3. Verify "ocs-storagecluster-ceph-rbd" is selected with access mode RWX and Volume mode Block 
4. Change the storageclass to "ocs-storagecluster-cephfs"
5. The whole windows goes blank
6. Refresh the page
7. Click Add disk
8. Verify "ocs-storagecluster-ceph-rbd" is selected with access mode RWX and Volume mode Block 
9. unselect "Apply optimized StorageProfile settings"
10. select RWO
11. select Filesystem
12. Change the storageclass to "ocs-storagecluster-cephfs"
13. This works

When changing the storage class field, the UI should also change the access mode and volume mode for the new storage class. Especially, when the new storage class does not support the previous settings.
