Symptoms

Revision versions of assets are not properly displayed when Flex Definitions are updated and mandatory attributes added.

Example replication steps:
Admin UI:
- login with fwadmin and for FirstSite2 go and navigate/expand Asset Type "Content C"
- enable revision tracking
- created a new "Content Definition" named "MikiCDsrTestPatch1" and added a few optional attributes like "FSIIImage + FSIINameAttr" and saved it
Contributor UI:
- created a new "Content" flex asset, assigned it to "fwadmin", named it "MikiTestV2" and choose to use the content definition "MikiCDsrTestPatch1", added an image for the Image attribute and saved it
- created a few versions (Edit save & check-in), some with modifications to the asset like adding a name for the Name attribute, made in total 4 versions
- checked/tested to preview all versions and all were rendered with success
Back to Admin UI:
- updated the "MikiCDsrTestPatch1" definition with a set of new mandatory attribute (Required) like "FSIIDescriptionAttr + FSIIHeadline etc", saved it
Back to Contributor UI:
- for the asset previously created tried to view the previous revisions using the "Show version" button and inspected all 4 versions
- revision versions were not properly rendered
